Warning: If you don't like seeing injuries that cause spurting blood, limbs that bend in the wrong direction, and brutal collisions, this probably isn't the slideshow for you.
If you don't mind seeing all of those things, however, than you've come to the right place. You'll see all of that and more in the 50 Most Devastating Injuries in Sports History.
It ain't pretty.
(Note: There have been instances of injuries in sports that have resulted in death. I've decided against including them in this slideshow, as such tragedies extend far beyond the category of "devastating injury.")
