Manny Gamburyan announced on his Twitter account that he has pulled out of a planned UFC 135 bout with Diego Nunes due to a shoulder injury.
Gamburyan (11-6) was expected to meet the featherweight Nunes (16-2) on the preliminary card of the night.
The main event for UFC 135 features Jon Jones defending his light heavyweight championship against former title-holder Quinton “Rampage” Jackson from Denver’s Pepsi Center on September 24.
A replacement for Nunes has yet to be announced.
“I hurt my shoulder and MRI is not looking good,” Gamburyan wrote. “I just wanna say sorry to all my friends and fans.”
