Return to contact sports should only occur after one week with no symptoms, both at rest and during activity, and following examination by a physician.
Contact sports are avoided for one week following unconsciousness of only seconds, and for two weeks for unconsciousness of a minute or more.
Studies of concussion in contact sports have shown that the risk of sustaining a second concussion is even greater than it was for the first if the person continues to engage in the sport.
A grade 1 concussion can usually be treated with rest and continued observation alone. The person may return to sports activities that same day, but only after examination by a trained professional
Contact sports, especially football, hockey, and boxing, are among those most likely to lead to concussion. Other significant causes include falls, collisions, or blows due to bicycling, horseback riding, skiing, and soccer.
Death
Contact sports, such as football and hockey, can damage the last remaining kidney, which will mean that that person will need a new kidney.

Most sports involve contact so the possibility of striking your unprotected head is high. Wearing a mouthguard cuts concussions down, the jarring of jaws causes concussions.
Nah ur fat mate
It affects the way you react to things... for instance if you get a concussion and you still have "concussion like symptoms" and if you get hit again and get another concussion that's some serious brain damage... they are trying to help keep everyone safe in the sports industry.
The levels of a concussion are referrred to as Grade 1, Grade 2, and Grade 3. Grade 1: Temporary disorientation, no loss of consciousness, all symptoms clear up in less than 15 minutes. Grade 2: Temporary disorientation, no loss of consciousness, symptoms persist for 15 minutes or more. Grade 3: Any loss of consciousness, whether for seconds or minutes. There's a good article on Concussion Management in Organized Sports that explains more. See http://www.headbraininjuries.com/concussion-management-sports.
Stop the game and get the refs attention. Go off the pitch and get assessed by the first aider. After a concussion you should rest for a 30 days with grade 3,or 24 hours with grade 1 recent studies show sports activity after a concussion slows down recovery time.
