Injured Athletes

Injured athletes can exhibit many or just a few of the signs and/or symptoms of concussion. However, if an athlete exhibits any signs or symptoms of concussion, the responsibility is simple: remove them from participation. “When in doubt sit them out.” It is important to notify a parent or guardian when an athlete is thought to have a concussion. Any athlete with a concussion must be seen by an appropriate health care provider before returning to practice (including dryland/weight lifting) or competition.
