We're giving you one final chance to turn back now because this leg break is not for the faint of heart.
Ante Delija was taking on Marcin Tybura for the M-1 heavyweight title at the weekend but the bout didn't last long as the Croatian felt his tibia crack after throwing a leg kick and fell to his back just three minutes into the first round.
As Tybura jumped into mount, the referee saw the horrific lump of bone through Delija's skin and waved the contest off as the challenger was in no condition to defend himself.
We tried to warn you!
