Todd Duffee will make his return to the Octagon this December, stepping in and facing Phil De Fries at UFC 155.

Duffee will take the place of Matt Mitrione, who accepted a bout with Roy Nelson for December.

UFC 155 takes place December 29 from Las Vegas, with UFC heavyweight champion Junior dos Santos defending his title against Cain Velasquez.

Duffee (7-2) went 1-1 in his brief UFC career, stopping Tim Hague before being stopped by Mike Russow. Duffee was dominating Russow before he got caught in the third round.

De Fries (9-1) has won two of his three Octagon bouts, including a submission over Oli Thompson earlier this year.
