Chael Sonnen is a lot of things: former two-time UFC middleweight contender, accomplished wrestler, professional trash talker.
But one thing he probably isn't? The new star of the acclaimed comedy series "It's Always Sunny In Philadelphia."
Still, the UFC superstar can be seen in the show's latest promotional video, in which the cast is replaced by other celebrities, including Andrew Dice Clay and Haley Joel Osment.
For those familiar with the show, in the promo, Sonnen replaces Dennis. For those not familiar with the show, Dennis is the over-confident leader of "The Gang" and part-owner of Paddy's Pub, a highly unsuccessful bar in the mean streets of Philadelphia.
Check out the above video to see Sonnen in action.
