Check out the video below to follow the journey of a young soccer player through a suspected concussion to understand the symptoms of concussions and the steps that should be taken before a player is allowed to return to the field. As the audience weaves between reality and what takes place in the player's mind, we see how both the physical and mental symptoms of concussions have very real effects.

A concussion can be difficult to recognize on the field. Most occur without a loss of consciousness or an obvious sign that something is wrong with a player’s brain function. They can occur at any time throughout games or practice, as a blow to the head or body from contact with the ground, the ball or another player. Working with leading physicians for more than a decade, U.S. Soccer created Recognize to Recover resources that will help coaches, players, parents and referees identify the signs and symptoms of concussion and immediately take action with the appropriate treatment.

Remove, Evaluate and Rest are key steps to treating a concussion or other head injury in soccer. When a concussion is identified quickly, it prevents the injury from getting worse, and prevents the player from staying off the field for even longer.

An athlete who experiences a blow to the head or body should immediately be removed for play and should not return to play until he/she is evaluated. When in doubt, the athlete should sit out.

Have a health care professional evaluate the athlete immediately. Do not try to judge the severity of the injury yourself.

Never rush a return to play. A return to play should only occur after an athlete has been cleared by a medical professional. If you rush the return, a player is at significantly higher risk for more problems in the future.
