10 Most Horrifying MMA Injuries Of All Time

9. Hominick's Haematoma

The title is "most horrifying," not "worst" MMA injuries, which is why Mark Hominick's second head earns a spot.

This grotesque sight emerged at UFC 129. The Canadian scrapper was José Aldo's first opponent following the UFC/WEC merger, and though he put up a valiant fight against the featherweight kingpin, he was overmatched. 'Scarface' couldn't put Hominick away, but he had his way with him, and Mark left with a gross, gross hematoma the size of a tennis ball.

Though visually striking, such injuries aren't usually enough to stop a fight. The cageside doctor deemed that despite its size, the hematoma didn't put Hominick at significant risk, and allowed the bout to continue. Thus, he made it all the way to the end of the five-round scrap with the bulbous build-up sticking out of his brow.

Hominick's hematoma was caused by arterial bleeding, and while such injuries can result in permanent disfigurement, his was successfully treated after the fight. Sadly, the Aldo loss would be the biggest moment of Mark's career. He lost his next fight in just seven seconds, and retired with a 1-4 UFC recover 11 months later.
