Brock Lesnar is done with MMA and here is the video and a decent transcription summary of what he had to say on ESPN.
“I have to say, first of all, thanks for having me. And that it was a very hard decision for me. I’m at a stage in my career where I want to… it was just hard, it was hard for me. And it’s hard to talk about it. The fighter inside of me wants to compete; the father, the husband… 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 will not be my last. I’m hanging up all thoughts… and that’s why I wanted to come here, I wanted it to be out of my mouth. I wanted people to hear me. It was a hard decision to make. It took me a year. I thought about this for a year. At the end of the day it’s all about me wanting to have fun. The money is great but the lifestyle… for me to get back in the Octagon, and for the last two months I’ve been training to get back into the Octagon, and felt physically great. But something lacked mentally. And that’s not good.”
“Absolutely, I talked with Dana (White), I talked with Lorenzo (Fertitta), I talked with Vince McMahon, I talked to my wife, I talked to my friends. I had many sleepless nights on what to do. At the end of the day it weighed heavyily on my heart that I was born to be an entertainer and I have fun doing it. I could go back to the Octagon and what am I going to gain? I was the UFC heavyweight champion of the world. Due to my illness my career got cut short, and that’s god telling you ‘hey, it’s time to move on.’ And maybe it’s a bump in the road for me but as the years went by it wore on my so much that the fighter inside of me didn’t want it to end that way, I didn’t want it to be that way. I didn’t want to leave the UFC on a losing streak. That’s just the competitive guy inside of me.”
“I’m officially closing the door on MMA, yes. And it was hard, it’s hard. I re-signed last night with the WWE. We’re pretty good at keeping secrets now, even in today’s age of technology. But we came to a conclusion last night. The offer on the table I just could not refuse. I think it’s fair to the fans (to find this out before WrestleMania). 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’s fair. It was public knowledge and it was out there that ‘what is Brock going to do?’ I went to the (Ronda) Rousey fight just to experience, to have that feeling of… it wasn’t a contractual move or a bartering pitch of any kind. For me, I just wanted to feel that energy. It just so happened that it was Ronda Rousey. If it would have been anybody I would have went to the fight.”
“No (Dana White didn’t have any words for me on the decision), absolutely not. You can’t force somebody to get into the cage and fight. That’s not the business. And that’s where I was. Was my heart and my head really into it? What are the reasons why I want to go in there? Because I don’t like the way it ended? Or really what is it? And at the end of the day I’m happy, I’m really happy where I’m at with the WWE.”
