Al Iaquinta steps in for injured Quinn Mulhern against Ryan Couture at UFC 164

Ryan Couture will remain on the UFC 164 card despite the loss of original opponent Quinn Mulhern.

Couture is slated to meet Ultimate Fighter 15 finalist Al Iaquinta in a lightweight bout in Milwaukee on Aug. 31. The news was first reported by the Las Vegas Sun.

Mulhern announced his fight pullout over Twitter on Tuesday, posting a picture of his fractured hand. In a follow-up to a fan's question, Mulhern attributed the injury to a "bad overhand right."

Couture (6-2), the son of five-time UFC champion Randy Couture, will be making his second Octagon appearance. He lost a second-round TKO to Ross Pearson on April 6 in Stockholm in his UFC debut, which snapped Couture's four-fight win streak.

Iaquinta, who trains with the Serra-Longo Fight Club, holds a record of 5-2-1. His last bout was a submission loss to Michael Cheisa in the TUF 15 championship fight on June 1 of last year.
