Joe Theisman
Joe Theisman spent his entire NFL career with the Washington Redskins, and during that time, he helped the team win two Super Bowls. Unfortunately, due to a catastrophic injury in 1985, his career, which could have been even longer and more illustrious, came to an end.
Theisman suffered a devastating injury when both bones in his lower right leg were broken after taking a hit from Giants linebackers Lawrence Taylor and Harry Carson. He’d never be able to play again after that.
Luc Nilis
Leg fractures are a common hazard for soccer players, as they throw their legs around with all their might. Luc Nilis had a long and successful career as a striker for Belgium and the Netherlands, but an injury ended his career prematurely.
He collided with goalkeeper Richard Wright in September of 2000, resulting in a double compound fracture in his right shin. Worse, the injury became infected at one point, resulting in the possibility of amputation. Needless to say, his professional career had come to an end.
