UFC president Dana White tweeted the news on Wednesday afternoon.
“WOW!! It never ends Carwin blew his knee out. Looking for a new opponent for Roy on the TUF Finale on FX,” White posted.
Carwin’s knee had come into question a few weeks ago, when he missed a promotional trip to England, but it was considered minor and he expected his knee to be good to go at fight time on Dec. 15.
This latest injury, however, is knocking him out of the fight, leaving the UFC, during one of its most injury plagued years ever, to search for a new opponent for Carwin’s coaching nemesis on TUF, Roy Nelson.
