He’s had a long and fruitful career full of ups and downs, and now Chris Leben is calling it quits.

“The Crippler” officially announced his retirement from MMA competition today on Ariel Helwani’s “The MMA Hour“, saying that, “These guys now, they are just a different breed of athlete than I am.”

One such athlete was Uriah Hall, who defeated Leben at UFC 168 on December 28, 2013. It was the TUF 1 veteran’s last fight in the Octagon, and it saw Leben take a beating at the hands of the TUF 17 star and quit on his stool before the second round could commence. The loss was Leben’s fourth in a row, with his last win coming via knockout over Wanderlei Silva at UFC 132 on July 2, 2011.

In 22 UFC appearances, Leben amassed a record of 12-10 (his overall record was 22-11).

Although he never won his season of The Ultimate Fighter, Leben was a memorable character who made a mark on the sport as an iron-chinned, iron-fisted brawler who’d bang with anyone. His spectacular wins – and losses – will undoubtedly grace the UFC’s highlight reels forever.
