WWE legend Brock Lesnar says he's retired after losing to Oba Femi at SummerSlam

"But the business and I still had some fuel in the tank. But Saturday for Brock Lesnar - that's it. That's it for me in the squared circle and for everything else."

"I was just a farm kid from South Dakota with big dreams and a big heart and a big-a-- chip on my shoulder," he added. "I'm just grateful. Grateful to be 49 years old and to have to be able to do what I did in this lifetime. I thank God and everyone that supported me."

Lesnar appeared to retire after losing to Femi the first time at WrestleMania 42 in April. He left his boots in the ring, signaling that he was finished. Weeks later, he came back to challenge Femi a second time and defeated him at Clash in Italy.

He will retire as a 10-time WWE champion and a two-time Royal Rumble winner. More importantly, he helped establish Femi as one of the top stars in the company.
