Football injuries include many of the leg (knee, ankle, hamstring, and many other types of injuries) and of the arm, they include the elbow, wrist, and forearm. While we may think that the leg is injured more often, the arm (wrist, forearm, and elbow) has many as well.
A recent study showed that four percent of football-related injuries affected the arm. The injuries, which most often are caused by tackling, blocking, or being tackled or blocked, affect the offensive linesmen most often, followed closely by the defensive linemen.
