The relentless rumor mill regarding Brock Lesnar and his future has finally come to a screeching halt, as the former UFC champ has announced he’s resigned with the WWE. In addition, the 37 year-old fighter has confirmed that he’s hanging up the MMA gloves, for good.

Lesnar appeared on ESPN SportsCenter on Tuesday, and during the segment, he announced the news. Here is some of what the storied wrestler had to say (quote via MMA

“I’m officially closing the door on MMA,” Lesnar said. “It was hard. I re-signed last night with the WWE. …We came to a conclusion last night and the offer on the table, I just could not refuse. I think it’s fair to the fans. It was my decision. I wanted to be fair to the fans to know that on Sunday at WrestleMania, I’m going home with that damn belt. It was public knowledge and it was out there that, ‘What is Brock going to do?’ I went to the Rousey fight just to experience – to have that feeling. It wasn’t a contractual move or a bartering pitch. I just wanted to feel that energy. It just so happened that it was Ronda Rousey.”

So, there you have it folks. Lesnar also relayed during the segment that he had been training for a possible return to the Octagon, but that “something lacked mentally.” The pro-wrestler said he talked to Dana White and Lorenzo Fertitta about returning to the UFC, but realizes that his urge to fight again was only because he didn’t want to leave MMA on a losing streak.

Lesnar left the UFC in 2011, after his well documented battle with diverticulitis, and a stoppage loss to Alistair Overeem. That defeat followed a 2010 loss to current champ, Cain Velasquez. The collegiate wrestling champ joined the promotion in 2008 and went on to win the heavyweight title.

It looks like we’ll never know how Lesnar’s return to the UFC would have gone, but regardless of whether he won or not, it would have been huge for the promotion.

During Lesnar’s UFC run he scored wins over Heath Herring, Randy Couture, Shane Carwin and Frank Mir. His only other defeat came against the latter in what was Lesnar’s Octagon debut.
