Ellenberger replaces Foster, meets Pierson at UFC 129
UFC officials announced the news earlier today.
Foster was forced to withdraw from the match up earlier this week due to medical conditions, and Ellenberger, eager to rise in the division, is looking to build upon a three-fight winning streak, which includes dominant decisions over Mike Pyle and John Howard.
Meanwhile, Pierson just recently debuted in the UFC, defeating Matt Riddle in dominant fashion at UFC 124. The victory was his sixth in a row and eleventh as a professional mixed martial artist.
UFC 129 is set for Toronto, Ontario, Canada on April 30 and features a main event between welterweight champion Georges St. Pierre and top contender Jake Shields. In the co-main event, Mark Hominick looks to rob the featherweight title from dominant champion Jose Aldo.
