While working as the team physician for the World Wrestling Federation, Dr. Unger was thrown through the set of Wrestlemania VII by 2 very strong and powerful female wrestlers, then hit over the head with a chair thrown by Hulk Hogan. This is when he decided that it might be best to simply develop his skills as a diabetologist rather than a mixed martial artist!
