Former Ultimate Fighter runner-up Al Iaquinta will step in and face Ryan Couture this August at UFC 164: Henderson vs. Pettis 2.
Iaquinta replaces Quinn Mulhern, who suffered a hand injury and was forced off the August 31 card. Iaquinta is returning from an injury himself.
The bout will likely be part of the prelims, which will air on FOX Sports 1 and Facebook.
Iaquinta (5-2-1) lost in the finals of TUF to Michael Chiesa. He was forced out of a planned bout with Joe Proctor earlier this year after a knee injury.
Couture (6-2) dropped his Octagon debut to Ross Pearson after competing in Strikeforce. He is the son of former UFC champion Randy Couture.
