12:14 PM ET 12.10 | UFC president Dana White believes B.J. Penn should retire after the two-time UFC champion lost via unanimous decision to Rory MacDonald at UFC on FOX 5. "B.J. will probably retire," he said. "I wouldn't mind seeing that. Rory looked better than he???s ever looked. You don't see body punches like that. B.J. is a warrior who doesn't give up. I've got so much respect for him. I'd like to see him retire. He's got plenty of money, he's got babies, (and) he has nothing to prove to anyone."
