It looks like Chael Sonnen was up to his old tricks last week when he said that he had no fight scheduled with Mark Munoz. In a press release sent out by the UFC, the company confirmed that Sonnen vs. Munoz is indeed on and it will be the co-main event of UFC on FOX 2 in January.

Originally hoping for another crack at Anderson Silva and the middleweight title following his victory over Brian Stann at UFC 136, Sonnen will need to win at least one more bout before he has the chance to go five rounds with the champ again. After being away from the action for over a year due to a drug suspension following his first fight with Silva, the Oregon native reminded the MMA world that he can back up his mouth with his skills as he dominated Stann with his wrestling in the first round and then submitted the former Marine with an arm triangle choke in the second round. Never one to shy away from the microphone, Sonnen challenged Silva in his post-fight interview, wanting to fight him on Super Bowl weekend in a “loser leaves town” bout.

With “The Spider” being sidelined due to an injury, Sonnen will have to go through one of the champ’s former sparring partners and another man who called out the middleweight king in his last bout. Winner of four straight bouts, Munoz turned in his most impressive performance to date at UFC 138 when he stopped Chris Leben at the end of the second round with an onslaught of ground and pound. Along with Leben, Munoz has defeated Demain Maia, C.B. Dollaway, and Aaron Simpson during his win streak.

The winner of the bout will most likely challenge Silva for the middleweight strap in mid-2012.

UFC on FOX 2 is scheduled for January 28 at the United Center in Chicago, Illinois. The night will be headlined by another #1 contender’s bout as former champion Rashad Evans takes on the undefeated Phil Davis in a light heavyweight showdown.
