10 Most Horrifying MMA Injuries Of All Time
6. Corey Hill's Snapped Leg
This may not be the UFC's most notorious leg break (we'll get to that one later), but it's just as likely to make you lose your lunch.
A contestant on The Ultimate Fighter's fifth season, Corey Hill lied about his amateur record to get on the show, and actually had his first professional fight during the competition. Despite this, coach Jeremy Horn thought he had the potential to become a force in the lightweight division. He then took Corey on as a protege after the show, and he graduated to full-time roster member in January 2008, knocking Joe Veres out at Fight Night 12.
Hill eventually fought Dale Hartt at the first Fight for the Troops event, and disaster struck 20 seconds into the second round. Hartt checked a leg kick. Hill's shin snapped on impact, and was soon wrapped around his opponent's calf, prompting Joe Rogan to scream himself hoarse while calling for the stoppage.
It took a full year for Hill to recover, and he never fought for the UFC again. He eventually retired with a 6-9 MMA record in 2015.
