WARNING:  This video isn't for the faint of heart.  It is a bit graphic.

With 6 minutes and 33 seconds left in the first half, Kevin Ware was playing the game of his life for entry into the Final Four.  He jumped to block a shot, came down awkwardly, and snapped his leg, just below the knee.

It was a "compound fracture", meaning the bone did indeed break through the skin. Again, watch at your own discretion.
