WARNING: This video contains some really graphic images of an MMA fighter with a broken leg.

If you decide to press play anyway, you'll see Ante Delija and Marcin Tybura taking part in the main event at M-1 Challenge 61 in Russia over the weekend. You'll then see Delija kick Tybura in the leg during the first round and…OMG. HIS LEG IS NOT SUPPOSED TO BEND THAT WAY.

Seriously, this is tough to watch. But it's yet another reminder about just how brutal things can get in the world of MMA.
