Event: Sin

Sid Vicious' career-ending injury in WCW's "Sin" event isn't too hard to explain. One look at the video can tell you that a person's leg isn't supposed to bend or snap or dangle like his does. The backstory to the injury plays a crucial role in its unfolding though, as Vicious had been asked by WCW management to broaden his array of moves before the match, suggesting he try some more aerial maneuvers. Reluctantly, Vicious agreed, though not without protesting that a wrestler of his size and type wasn't equipped to attempt the high-flying techniques that they wanted. He turned out to be right.
