December 15th’s TUF 16 Finale in Las Vegas now has a new headliner after Shane Carwin pulled out due to a knee injury.

A fomer TUF competitor himself, Matt Mitrione will now step in to face the man who won the season he featured in, Roy Nelson.

Reports suggest that Cheick Kongo was actually offered the fight first, but after he refused Mitrione was given the opportunity instead. Prior to that Mitrione had been in the UFC’s bad books after refusing a short-notice fight with Daniel Cormier over at Strikeforce, so this may be a chance to get back in their good graces again.

Mitrione is in fact coming off a loss to Kongo back in October of last year taking him to 5-1 for his career as a whole, while Nelson KO’d Dave Herman at UFC 146 in June, but has patchy 4-3 record in the UFC overall.
