The UFC’s biggest pay-per-draw and former heavyweight champion Brock Lesnar announced his retirement tonight after his loss to Alistair Overeem in the main event of UFC 141.

Lesnar confirmed his decision to Joe Rogan in the Octagon after being TKO’d by a liver kick in the first round by the Dutch striker, denying him another chance to fight for the heavyweight title that once rested around his waist.

“I’ve had a really difficult couple years with my disease,” Lesnar stated. “And I’m officially going to say this is the last time you’ll see me in the octagon.”

Lesnar has of course now battled back from the Diverticulitis illness on two separate occasions during that period, eventually requiring him to have 12 inches of his colon removed earlier this year.

Dealing with that while also attempting to compete at the highest level in mixed martial arts competition has clearly been a major challenge for him and so it’s no surprise that he is now looking to hang up his gloves.

Though he hadn’t said so pre-fight, he revealed afterwards that it was in fact a decision that was always going to come sooner rather than later regardless of the way this fight went.

“I promised my wife and my kids…if I won this fight I would get a title shot and that would have been my last one but if I lost tonight…”

At that point he started to show signs of getting emotional, thanked the crowd, Overeem and then walked out of the Octagon for the last time.
