That would obviously be Football (:
The most common wrestling injuries in this sport are neck injuries and back injuries and shoulder injuries and calf injuries and groin injuries and foot injuries especially.
the contact sport that has the most injuries in my opinion would be soccer.
Rugby is the violentest sport and injuries occur alot.
Since boxers get hit in the head a lot (and the object of the sport to is knock out your opponent by a blow to the head) there are a lot of concussions and brain injuries.
Cheerleading or gymnastics is the most dangerous sport and it has been proven
baseball is the sport with the least injuries because all you do is run around bases. The most common injury in baseball is a hamstring
Some serious injuries are a boken spine, bad head injuries, and bad internal injuries.
