After emerging as a heavyweight to watch, Ultimate Fighter alumnus Matt Mitrione has become one of the division’s forgotten faces after an extended absence from action for a handful of health-related reasons. Fortunately, though Mitrione hasn’t fought since an October loss to Cheick Kongo, he will at least be able to get his hands dirty before the conclusion of 2012.

According to an official announcement, Mitrione will mix it up with Philip de Fries at UFC 155. No reason was offered in terms of what happened to Mitrione’s previously announced rumble with Rob Broughton at UFC on FX 5, though the show did recently receive an influx of fights due to the cancellation of UFC 151 and may have simply been overbooked.

The 5-1 “Meathead” has never fought outside of the Octagon, racking up wins in each of his first five professional pairings including four by way of knockout. Comparably, De Fries is 9-1 and was last seen submitting Oli Thompson earlier this month at UFC on FOX 4.

UFC 155 is scheduled for December 29 and is expected to feature Junior dos Santos defending his heavyweight title against former champion Cain Velasquez in the event’s headlining slot.
