And who knows how many other athletes didn't return?
An educational consortium was also established to help former athletes return to school to finish their degrees as well.
It said two athletes had returned home and the three others were here.
When the Games were over, athletes returned home to parades and receptions.
For example, professionals recommend that athletes not return to play before symptoms of an initial head injury have resolved.
According to consortium statistics, more than 2,527 professional athletes have returned to school since 1991.
In the past, the decision to allow athletes to return to participation was frequently based on the grade of concussion.
Hence, it is difficult to determine when an athlete can return to sports after his/her injury.
At the end, the athletes and the technical committee will return home to continue the training and disseminate knowledge acquired.
Wounds must be covered with an occlusive dressing that remains intact during play before athletes return to competition.
