Athletes are monitored for concussions during sports games in several ways. Team medical staff and coaches keep a close eye on players, watching for any signs of possible concussion, such as appearing dazed or confused, stumbling, or displaying uncoordinated movements. Many sports leagues and schools also have concussion protocols in place that require players suspected of having a concussion to be immediately removed from play and assessed. Some sports use sideline assessment tools like the Sport Concussion Assessment Tool (SCAT), which includes a series of tests to evaluate an athlete's physical and cognitive function.
