5 WWE Superstars whose careers were derailed by injuries or illness

#2 Bret Hart

Bret Hart's career came to a bad end

Bret 'The Hitman' Hart's career is one filled with loss and regret.

He was the best WWE Superstar during his time in the company, as one of the leaders of a new breed of wrestlers, who focused more on technique rather than muscle. He helped WWE during one of their toughest times and had some of the best matches in the company's history against Shawn Michaels, Stone Cold, and his own brother, Owen Hart.

However, when he left after the 'Montreal Screwjob' to go to WCW, things were supposed to be even better for him. After all, the heat from the Montreal Screwjob was sure to see him become their top superstar?

That was not to be. He did not debut in WCW for a while and the heat had died down a little. What was worse, he did not have the best run in the company. Here, just as he was slowly gathering momentum, he entered a match against Bill Goldberg.

Goldberg was known for being notoriously stiff in the ring. A stiff kick saw Bret Hart knocked out with a concussion. It was an injury that Bret Hart would never recover from. The injury was serious and it was ruled he could not continue in the ring. Bret Hart had to retire early, bringing an unceremonious end to an otherwise glorious career.
