2018-19 Concussion Data Reinforces Trends
September 26, 2019

Data on student-athlete concussions collected by the Michigan High School Athletic Association from member high schools during the 2018-19 school year further reinforced findings from the first three years of reporting, and will contribute significantly as a number of MHSAA-associated groups work during the coming year to reduce the incidence of those injuries.
The 2018-19 concussion report found student-athletes at MHSAA member high schools encountered a total of 3,686 head injuries during the past school year – 3.0 percent more than in 2017-18. But that slight increase barely affected two key ratios. The number of injuries per member school was 4.9, up just a tenth of a percent from 2017-18, and for the second straight year only 1.3 percent of participants in MHSAA sports experienced a head injury, still down from 1.4 in 2016-17 and 1.6 percent the first year of the study. Total participation in MHSAA sports for 2018-19 was 281,992 – with students counted once for each sport they played.
The MHSAA has continued to invite Michigan’s universities, health care systems and the National Federation of State High School Associations (NFHS) to take part in analyzing the data and resulting questions that have arisen during the past three years. The 2018-19 results will be examined by the MHSAA’s newly-formed Sports Medicine Advisory Committee and also undergo analysis by representatives of Michigan State University’s Institute for the Study of Youth Sports. Furthermore, the MHSAA is directing its sport committees to study the data as they consider adjustments that could be made to rules for practice and competition.
“The 2018-19 concussion survey further reinforced the findings and trends we have seen emerge; not only in specific sports, but across all of our activities – and this latest set of results also raises new questions,” MHSAA Executive Director Mark Uyl said. “We must continue to look at how changes to playing rules and improvements in equipment may be beneficial moving forward, and also how we can further educate administrators, coaches, athletes and parents to identify and provide treatment for these injuries as soon as possible. We also are excited for the opportunity to have more eyes on these results as we continue to explore more ways to make our games safer.”
As first mandated in 2015-16, member schools are required to report head injuries to the MHSAA identifying the sport that each student-athlete was participating in and whether the injury was sustained during practice or competition. Schools also are required to designate at which level – varsity, junior varsity or freshman – the injury occurred.
The full report of all head injuries experienced during 2018-19 by student-athletes at MHSAA member high schools – including percentages by sport (per 1,000 participants), gender and team level, as well as data tracking when athletes returned to play – is available on the Health & Safety page of the MHSAA Website.
Keeping with the first three years of this survey, the MHSAA continued to receive data from more than 99 percent of its member high schools after the fall, winter and spring seasons. Member junior high and middle schools also were allowed, although not mandated, to report their head injuries; and those findings are not part of the published report.
Boys in 2018-19 experienced 2,404 – or 65 percent – of concussion injuries, just a percent less than during 2017-18, and not surprisingly as boys have a much higher participation in contact sports. More than half of head injuries – 59 percent – were experienced by varsity athletes, a slight increase of three percent from the previous year. A total of 2,441 head injuries – or 66 percent – came in competition as opposed to practice. Just more than half took place during either the middle of practice or middle of competition as opposed to the start or end, and 51 percent of injuries were a result of person-to-person contact.
The MHSAA also asked schools to report the number of days between the head injury and the athlete’s return to activity – and the two largest groups returned to activity after either 6 to 10 days of rest (24 percent) or 11 to 15 days (23 percent). All of these findings were within 1-3 percent of those discovered from the 2017-18 data.
Contact sports again revealed the most head injuries. Ranking first was football, 11 and 8-player combined, with 44 head injuries per 1,000 participants – an increase of three per 1,000 from 2017-18 but the same ratio as 2016-17 and still down from 49 head injuries per 1,000 football participants shown by the first study in 2015-16. Ice hockey again revealed the second-most injuries per 1,000, with 35 (also up three from a year ago but still down from 36 injuries per 1,000 from 2016-17 and 38 per 1,000 in 2015-16), and girls soccer was third with 25 head injuries per 1,000 participants for the second year in a row. Wrestling followed with 22 head injuries per 1,000 participants.
Continuing a noticeable trend of the last few years, the next three sports to show the highest incidences of head injuries were girls sports – girls lacrosse, competitive cheer and basketball also revealed 20 per 1,000 participants, although basketball was down two injuries per 1,000 participants or nearly 10 percent from the previous year. Boys lacrosse (16), boys soccer (14), girls volleyball (11), softball (11) and gymnastics (10) also showed double-digit head injuries per 1,000 participants.
Females again reported significantly more concussions than males playing the same or similar sports – soccer, basketball and baseball/softball. Female soccer players reported nearly double the concussions per 1,000 participants as male soccer players (25 to 14), while female basketball players reported nearly triple the number of concussions per 1,000 participants (20 to 7). Softball players also reported nearly triple the concussions per 1,000 participants of baseball players (11 to 4).
Schools report possible concussions online via the MHSAA Website. Reports are then examined by members of the MHSAA staff, who follow up with school administrators as those student-athletes continue to receive care and eventually return to play. Student privacy is protected.
The reporting of concussions is part of a three-pronged advance by the MHSAA in concussion care begun during the 2015-16 school year. The MHSAA completed in spring 2017 the largest-ever state high school association sideline concussion testing pilot program, with a sample of schools from across the state over two years using one of two screening tests designed to detect concussions. The MHSAA also was the first state association to provide all participants at every member high school and junior high/middle school with insurance intended to pay accident medical expense benefits – covering deductibles and co-pays left unpaid by other policies – resulting from head injuries sustained during school practices or competitions and at no cost to either schools or families.
Previously, the MHSAA also was among the first state associations to adopt a return-to-play protocol that keeps an athlete out of activity until at least the next day after a suspected concussion, and allows that athlete to return to play only after he or she has been cleared unconditionally for activity by a doctor (M.D. or D.O.), physician’s assistant or nurse practitioner.
In addition, the MHSAA’s Coaches Advancement Program – which includes courses that must be completed by all varsity head coaches hired for the first time at a member school – provides substantial instruction on concussion care. Separately, rules meetings that are required viewing for high school varsity and subvarsity head and assistant coaches at the start of each season include detailed training on caring for athletes with possible head injuries.

Fall Sports Practices Begin Next Week
August 3, 2018
By Geoff Kimmerly
Special for Second Half
More than 100,000 student-athletes will begin practices next week in nine sports in which the Michigan High School Athletic Association sponsors postseason tournaments, signaling the beginning of the 2018-19 Fall sports season.
Practice in football may begin Aug. 6 for all schools wishing to begin regular-season games the weekend of Aug. 23-25. Schools must have 12 days of preseason practice at all levels before their first game, over a period of 16 calendar days before the first kickoff.
Practice sessions for all other sports begin Wednesday (Aug. 8). In golf and tennis, competition may commence no earlier than after three separate days of team practice, and not before seven calendar days. The first day competition may take place in golf and tennis is Aug. 15. In all other fall sports, contests can take place after seven days of practice for the team and not before nine calendar days. The first day competition may take place in cross country, soccer, swimming & diving, and volleyball is Aug. 17.
This fall, two football game dates again precede Labor Day, and a number of MHSAA schools will play their first varsity games Thursday, Aug. 23. In Week 1, 146 varsity games will be played on Thursday, 152 contests will be played Friday, and 12 games will be played Saturday. During the second week, one game will be played Wednesday, 245 games will take place Thursday, 62 will be played Friday, and one contest is scheduled for Saturday.
For fall sports, perhaps the most discussed change will concern MHSAA Tournament classification in volleyball. For the first time, volleyball teams are classified in four equal divisions instead of the traditional Class A-B-C-D. Class no longer will be used to organize the postseason for any sport, including girls and boys basketball in the winter. All other sports previously had switched from classes to divisions.
While most fall sports face at least minor rules changes this season, a few of the most noticeable adjustments in fall sports will come in football, volleyball, boys soccer and girls swimming & diving.
• In an effort to improve football pace of play by reducing re-kicks after a free or scrimmage kick (generally kickoffs or punts, respectively), an option has been added allowing the receiving team to accept a penalty and tack on the awarded yardage to the spot where the kick or punt return ended. This option incentivizes the receiving team to forgo a re-kick, and joins three other options after a penalty on the kicking team. The receiving team also may continue to accept a penalty from the previous spot and have the kicking team re-kick; and on kickoffs that travel out of bounds, the receiving team may continue to accept the ball and begin possession 25 yards from where the kickoff occurred or decline the penalty and begin possession where the kick flew out of bounds.
• Additionally for football, players who fail to properly wear required equipment or are missing required equipment during a down shall be replaced for one down rather than incur a yardage penalty. Previously, a penalty was assessed for delay of game in this scenario. If a player’s proper or legal equipment has become improperly worn through use and prompt repair is possible and does not cause a delay in game, that repair may be made without the player being replaced for the next down.
• A change in volleyball will allow teams to substitute for an injured/ill player prior to a replay; previously a replay would take place with no changes on the floor after the point was originally contested.
• Also in volleyball, with an eye on risk minimization, teams will be allowed to warm-up between sets only in their playing area and may not hit volleyballs over the net into the opponents’ playing area.
• For soccer – both boys this fall and girls in the spring – teams may continue to play up to two multi-team events every season, but beginning this fall a multi-team event can include two full 80-minute games the same day and still be counted as only one of a team’s 18 regular-season contests. Teams also may continue to play multi-team events with 30-minute halves and no more than 180 minutes total in one day (for example, three games with 30-minute halves) and call it just one contest of the 18.
• Another significant soccer change will switch the home team to wearing the dark uniform and the away team to wearing the white uniform. The change was made to allow home teams to wear their school colors – it does not require teams to purchase new uniforms, but only switches which team wears dark and which wears white.
• Also for soccer, a change has been made to the penalty when a player is whistled for denying the other team an obvious goal-scoring opportunity. If a player, in the penalty area, commits an infraction while attempting to play the ball, and that infraction results in a penalty kick, that offending player will receive a yellow card – previously this would have been a red card. If the player is not attempting to play the ball when an infraction is called in the penalty area that results in a penalty kick, the offending player still will receive a red card along with the opposing team being awarded the penalty kick.
• In swimming & diving regular-season competition, a pair of changes will provide more opportunities for divers. The diving event in dual, double-dual or other multi-team non-championship competition has been limited to six dives, but now may be expanded to an 11-dive competition – giving divers another opportunity to prepare for the 11-dive competitions at the MHSAA Qualification Meets and Finals levels. Also, while diving traditionally has been placed in the middle of the event order of a dual or other regular-season meet, it may now be conducted first, last or simultaneously with the swimming events. (Both require prior mutual consent by competing teams and officials.)
• Also in swimming & diving, visible 16.4-yard (or 15-meter) marks must be made visible on both sides of the pool deck to assist swimmers during competition.

The MHSAA is a private, not-for-profit corporation of voluntary membership by more than 1,500 public and private senior high schools and junior high/middle schools which exists to develop common rules for athletic eligibility and competition. No government funds or tax dollars support the MHSAA, which was the first such association nationally to not accept membership dues or tournament entry fees from schools. Member schools which enforce these rules are permitted to participate in MHSAA tournaments, which attract more than 1.4 million spectators each year.
