UFC President "I want Penn to retire"

"I want B.J. Penn to retire," White said.
"Dude, you've won belts in two different weight classes, you're one of the greatest ever and you became a huge superstar. You have money, you have a beautiful family. But, it's hard man, it's hard to walk out of that arena that is packed with everyone screaming your name and you're making tons of money. It's hard to walk away from that -- really hard to walk away from that."

"B.J. is too tough for his own good," White said. "B.J. might not get knocked out, but the shots that B.J. took would have knocked out a normal human being. He's had his head bounced off the canvas like a basketball by Matt Hughes, Georges St. Pierre and Rory MacDonald just did it to him. B.J. Penn has left that Octagon looking like a fucking alien. He's too tough for his own good. You don't knockout B.J. Penn -- he absorbs every amount of punishment you give him. It doesn't mean he hasn't taken any damage … he's taken a lot of damage. And I don't want to see him take any more."
