UFC president Dana White made an announcement during the weigh-ins Thursday evening for The Ultimate Fighter: Live Finale.

The announcement was the retirement of Kenny Florian from active competition. Florian fought for three UFC titles in four weight classes after his time on The Ultimate Fighter.

“Had I not met him that night in Boston, who knows if he would have ever got to the UFC,” White said. “He’s been an amazing ambassador to this sport and the UFC.”

Florian has been dealing with a severe back injury suffered last November in training. He said he has been unable to get back to his normal training, including re-injuring it a few weeks ago.

“I don’t know what I would have done if Dana wasn’t there. All I ever wanted to do at that time was be a mixed martial artist full time,” Florian said. “I am just so thankful to everyone at Zuffa for everything they have done.”

Florian, who finished 16-6 in his career and 12-5 in the UFC, claimed seven victories via rear-naked choke. He was unable to pinpoint one moment as a memorable one, saying, “there was a lot of great moments.”

Florian will remain in his role as a commentator for the UFC, along with coaching in Los Angeles where he will be opening a gym in the near future.
