Former UFC Heavyweight Champion and current WWE World Heavyweight Champion Brock Lesnar announced on SportsCenter that he will not return to his MMA career in the UFC, but will remain with the WWE. Below are some quotes from his exclusive interview with ESPN's Michelle Beadle.
Lesnar on coming to the decision to not return to a career in MMA and remain with WWE...

"It was a very hard decision for me...it's hard to talk about it. The fighter inside me wants to compete...You know I'm an older caveman now, so I make wiser caveman decisions. So I'm here to say that my legacy in the Octagon is over, however my legacy this Sunday at WrestleMania will not be my last."

"It was a hard decision to make. It took me a year...For the last two, two and a half months I've been training to get back into the Octagon and felt physically great, but something lacked mentally and that's not good."

"I had many sleepless nights on what to do and at the end of the day, it weighed heavily on my heart. I was born to be an entertainer and I have fun doing it. I could go back to the Octagon, but what am I going to gain? I was the UFC Heavyweight Champion of the World...."
