Stephan BonnarLight heavyweights Stephan Bonnar (12-4) and Jon Jones (6-0) will clash at UFC 94 on January 31st in Las Vegas, according to Five Ounces of Pain.

Bonnar returns to the octagon for the first time in over a year, after a knee injury knocked him out of an April bout with Matt Hamill and required surgery which kept him out of action for all of 2008. Prior to the injury Bonnar rebounded from back-to-back losses to Rashad Evans and Forrest Griffin to win two-straight bouts over Mike Nickels and Eric Schafer.

A high school and junior college wrestling champion, Jones is one of the youngest fighters on the UFC roster at just 21-years-old. Despite already having compiled an undefeated 6-0 professional record, including a decision win over Andre Gusmao in his UFC debut at UFC 87 in August, Jones has been fighting professionally for just six-months.

UFC welterweight champion Georges St-Pierre and UFC lightweight champion BJ Penn clash for the 170-pound title in the main event of UFC 94, which will air live on pay-per-view.
