8. Eric Bostrom

Injury Sustained: Sliced thigh
Raced In: AMA Superbike, AMA Supersport
Complex Says: In September 2010, the world was almost down one Bostrom Brother when Eric Bostrom had a nasty crash with Jordan Suzuki rider Brett McCormick. Somewhere during the course of the crash, Bostrom's footpeg broke and ripped his right thigh open, coming within a mere two centimeters of his femoral artery and associated nerves.

Don't believe a mere slice can be so nasty? The Adventure Rider Forums thread about the accident was titled, “Eric Bostrom Attacked By Shark.” On TV, it didn't look so bad, but close-ups of the wound aren't pretty. Who went back to racing after healing? Take a guess.
