“Is CM Punk going to be a guy who is going to stay in the UFC and continue to fight? Probably not,” White said on UFC Tonight, per Tristen Critchfield of Sherdog.com. “But he wanted to try it. I like the guy. I respect the guy. He wanted to fight in the UFC. He wanted to do it. He trained for two years, and he did it.”
“There’s been situations like Brock Lesnar who came in and wanted to do it, and obviously that one turned out well,” he said. “Then obviously we had the CM Punk thing. It just depends. I wouldn’t say that I’m looking for retired NFL players for pay-per-view or anything like that. I just don’t know what the real interest is in seeing some of these guys fights or even if it makes sense.”
"I know he wants to get back on the mat and keep working. I had a plethora of promoters reach out to me but I'm not his manager. People have shown great interest in working with him."

Bellator will certainly be looking to pick him up as he'd bring in viewers wherever he goes. I don't know whether he'd want to go there though. Bellator are the TNA of MMA, basically.
