Light heavyweights Randy Couture and Mark Coleman are expected to meet in the main event of UFC 109 on February 6 in Las Vegas, according to Sherdog, marking the first time UFC Hall of Famers will square off inside the Octagon.

Couture is coming off a win over Brandon Vera this past Saturday at UFC 105, while Coleman defeated Stephan Bonnar in his most-recent bout in July.

“Coleman,coleman,coleman to bad he sissies out!!! Who’s next??? I’m kicking someone’s ass on Nov 21st!”
