9. Bully Ray
Bully Ray, better known as one half of the Dudley Boyz in ECW and WWE, suffered a quad tear while wrestling for TNA. Fortunately for him, it was only a partial tear. He worked through the injury, which pretty much establishes him as either a fool, or an undeniable badass —or maybe both.
It's a sobering reminder that when a wrestler is on the road, wants to support his family, and doesn't want to slow his push, he'll go to inhuman lengths to work through pain.
