Another one bites the dust.

Just three weeks away from fight night, Stephen Thompson has been forced to pull out of his scheduled bout against Besam Yousef at UFC 154: "St. Pierre vs. Condit," which goes down on Sat., Nov. 17, 2012, at the Bell Centre in Montreal, Quebec, Canada.

The culprit is a torn meniscus that will force "Wonderboy" to go under the knife on Monday, according to MMAFighting.com. His recovery time is somewhere around eight weeks.

There has been no word on the injury from the UFC, meaning no new opponent has been announced for Yousef, who was looking to rebound from a second round submission loss in his Octagon debut back at UFC on FUEL TV 2 in April of this year.

The bout was scheduled to take place on the Facebook broadcasted portion of the preliminary card.

UFC 154 features a welterweight championship unification bout pitting the recently rehabbed Georges St. Pierre looking to reclaim his 170-pound throne from sit-in interim strap-hanger Carlos Condit. Martin Kampmann vs. Johny Hendricks is scheduled for the co-main event.
