When it comes to injuries, football is riddled by more than concussion problems. "The most common thing is a musculoskeletal injury," Dr. Edward Laskowski, co-director of the Mayo Clinic Sports Medicine Center, told CBS News.
"The ligaments are at risk in football. The ACL [anterior cruciate ligament of the knee] is one of the more problematic injuries that you can have. It's often not a result of contact but of rapid deceleration; change of direction. You're running down field, you plant, then change direction significantly, pivot, and that can create stress on ligaments to the point that they tear," said Laskowski, who is also a consultant to the NHL Players Association and an Olympic team physician.
He said a number of positions on the field are at risk: halfbacks, wide receivers, safeties, and quarterbacks.
"In linemen, we don't see ACL injuries as much because they're not going down the field as often," Laskowski said.
