UFC has been embroiled in lawsuits with several former fighters.

One of the worst things that happens on a regular basis in MMA, is injuries. Now, that comes as no surprise, given the fact that they're fighting in the cage. Still, these ten injuries were absolutely horrific and completely shocked and devastated fans in the arena.

10 Devin Clark (vs. Ion Cutelaba)

At UFC Vegas 37 in September 2021, light heavyweights Devin Clark and Ion Cutelaba faced off. 'The Hulk' dominated that bout, ultimately handing the wrestler a unanimous decision defeat. In the process, Cutelaba destroyed Clark's face.

Specifically, Clark's teeth were completely smashed as a result of a massive knee in the second round. The light-heavyweight's teeth were mangled, and he reportedly broke his jaw as well.

The rivalry between Miesha Tate and Ronda Rousey was an incredible one. Their first meeting came at Strikeforce in 2012, with 'Cupcake' as the defending bantamweight champion. Predictably, Rousey won by first-round armbar.

However, Tate didn't tap nearly as quickly as she should've. By trying to fight through the submission, Rousey wound up dislocating her rival's elbow. The site of Tate's arm, post-fight was a rough to look at for viewers.

8 Jon Jones (vs. Chael Sonnen)

The rivalry between Jon Jones and Chael Sonnen was a lopsided one. 'Bones' wound up dominating the longtime trash-talker, securing a first-round knockout win over him in April 2013. As it turns out, the most damage inflicted on Jones was by himself.

While scrambling for a takedown, Jones badly broke his big toe on his left foot. While that doesn't sound like a terrible injury on paper, the replay showing how it happened was horrifying. You know it's bad when Jones won't even look at his foot post-fight.

7 Conor McGregor (vs. Dustin Poirier)

Conor McGregor and Dustin Poirier's trilogy bout ended in catastrophe. Their first fight, McGregor won by technical knockout and in the second Poirier got revenge with a knockout of his own. Their third meeting ended in injury in the final seconds of the first round.

McGregor famously broke his leg and stepped back on the broken limb in a terrifying sight. Over two years on from the devastating injury, 'The Notorious' has yet to return to the cage.

6 Alistair Overeem (vs. Jairzinho Rozenstruik)

The Legend's Cut Was Horrifying

In December 2019, Alistair Overeem faced the rising Jairzinho Rozenstruik. The longtime UFC heavyweight contender was up on the scorecards heading into the fifth, and final round. However, Rozenstruik scored a buzzer-beater knockout, with a Superman punch.

That one shot also disfigured Overeem's face. The legend had a cut that busted his lips open, and the shot of the heavyweight post-fight with the injury was grotesque. It's more of a cosmetic issue compared to something like McGregor's leg break, but it's still not a pretty sight.

5 Evangelista Santos (vs. Michael Page)

The young Michael 'Venom' Page was on the rise heading into 2016. That July in London, he faced longtime veteran and Strikeforce title challenger Evangelista Santos. In round two, 'Cyborg' was flattened with a flying knee, and Page went viral for throwing a Pokeball at his opponent in celebration.

Post-fight, Santos revealed the horrifying result from a hospital room. The Brazilian suffered a fracture in his skull, with a clear dent from the flying knee from the British fighter.

The legendary rivalry between Kazushi Sakuraba and the Gracie family produced classic after classic. In August 2000, the Japanese pro wrestler faced Renzo Gracie, in another chapter of their storied feud.

The fight was back and forth but saw Sakuraba get Gracie into a kimura. The Brazilian was prideful and refused to tap. As a result, Sakuraba began cranking it even more, snapping his arm, and securing the submission win.

3 Corey Hill (vs. Dale Hartt)

This Leg Break Was Absolutely Horrifying

Over the years, Corey Hill's leg break vs. Dale Hartt has been kind of forgotten. It makes sense, given the premature passing of 'The Real Deal', and 'The Demon' only having a three-fight UFC stint.

Still, this 2008 bout produced arguably the most gruesome injury in MMA history. Hartt checked a kick from Hill in the second round, and instantly, the latter's leg snapped. As a result, he was out of action for two years, and his career was never the same.

2 Anderson Silva (vs. Chris Weidman)

The Legend Was Never The Same After UFC 168

Few injuries were more devastating than Anderson Silva's leg break against Chris Weidman in December 2013. As the story goes, 'The Spider' was on the comeback trail, and hoping to regain the title he lost earlier that year.

However, in the second round, disaster struck. Weidman checked a kick from Silva, who instantly collapsed in agony. While the Brazilian went on to have great performances after this point, his career never fully recovered.

1 Chris Weidman (vs. Uriah Hall)

Eight Years After Breaking Anderson Silva's Leg, Weidman Suffered The Same Fate

UFC 261 was supposed to be a night of celebration. The card was the first with a live crowd after the COVID-19 pandemic, and it was stacked. Sadly, the main card kicked off with one of the most grotesque injuries in MMA history.

In the opening seconds of Chris Weidman vs. Uriah Hall, the former champion broke his leg after having his kick checked. Nearly a decade after breaking Anderson Silva's leg, the wrestler suffered the same fate.
