3. Ryan Sweeney (2012)
Another MLB star, another ridiculous self-inflicted injury. Sweeney played for the Red Sox in a victory over the Tigers but stole the headlines for an idiotic reason. Cody Ross replaced the right-fielder in the ninth inning of the game. This prompted fans to think that the franchise had traded him before the deadline. But the player had punched a door and broke a knuckle on his hand.

Of course, this injury put him on the disabled list because he couldn’t play. “I feel like I just let the team down if it’s bad,’’ Sweeney said via Boston.com. “I feel terrible right now. Obviously, when you hit something, you just have so much adrenaline going and you don’t know what happened. Afterward, it just hurt.” Finally, he discovered that punching hard objects is a bad idea.
