When you play sports, you always run the risk of getting an injury. When you play at the highest level, at top speed and intensity, you run the risk of getting an injury so gruesome that it's hard to watch.
I have compiled a list of the 25 most gruesome injuries in sports history. There are some out there I left off only because I couldn't find a clip of, or I already had too many videos of someone's leg snapping in half. Needless to say This slideshow is not for the faint of heart. The pictures and videos may be difficult to see. Proceed at your own risk.
