This is the fourth time Ferguson and Nurmagomedov have been slated to fight, but it has not come to fruition.

UFC president Dana White told ESPN that Ferguson tore his LCL and needs surgery.

“He actually tore it off the bone, he’s gonna need surgery on his knee,” White said.

“As soon as these guys step in the ring and throw a punch, it’s on for the title,” White said. “Whoever wins, wins the title and we’ll see what happens with Conor over the next several months. I know he had expressed some interest in fighting in September.”

The current UFC Interim Featherweight Champion, Holloway will look to capture his second title, as he steps in to fight Nurmagomedov on less than two weeks notice.
