Ellenberger was removed from the card on Friday and will now face Robbie Lawler at UFC 173 on May 24 in Las Vegas. UFC officials confirmed the bout to ESPN.com after an initial report by USA Today.
It's the second time a scheduled fight between Ellenberger and Saffiedine has fallen through. They were supposed to headline a UFC event in January, but Ellenberger was forced off the card by a hamstring injury.
Ellenberger (29-7) hasn't fought since suffering a unanimous decision loss to Rory MacDonald in July. Prior to that, he had gotten himself into title contention with a first-round knockout over Nate Marquardt at UFC 158.
Lawler (22-10) fought for the vacant UFC welterweight title on March 15. The American Top Team fighter lost a narrow unanimous decision to Johny Hendricks. He is ranked the No. 2 welterweight in the world according to ESPN.com.
