Manny Gamburyan, who has made 13 appearances inside the Octagon, has been forced out of a planned UFC Fight Night 94 encounter with Alejandro Perez.
Perez will remain on the September 17 card from Hidalgo, Texas, as he welcomes Albert Morales to the UFC. The card, which takes place inside the State Farm Arena, airs on FOX Sports 1 and UFC Fight Pass, and marks the first time the promotion has stopped in Hidalgo.
Morales (6-0) is a 25-year-old from California who has competed in Bellator, the World Series of Fighting and Resurrection Fighting Alliance. Two of his six career wins came with Bellator, while five of his six have been stoppage triumphs.
Perez (17-6) sports a 3-1 UFC mark, which includes a 2014 win over Jose Quinonez, which was in the finals of The Ultimate Fighter: Latin America. The 26-year-old from Mexico rebounded from a loss to Patrick Williams by besting Scott Jorgensen and Ian Entwistle in his last two matches.
