Chad Mendes has lost his scheduled opponent for UFC 157: Rousey vs. Carmouche, as Manny Gamburyan has suffered an injury. The card goes down February 27 from Anaheim.
According to MMAWeekly.com, Gamburyan suffered a broken thumb in training and will be out for an extended period of time. The veteran is 12-7 in his career.
It remains unknown if an opponent will be found for Mendes, who has won two straight since a loss to UFC featherweight champion Jose Aldo in early 2012.
UPDATE: Gamburyan confirmed with MMAjunkie.com that he also fractured his elbow, along with the thumb injury, and will be sidelined for at least three months.
