Garry, the No. 7 contender in the division below champion Leon Edwards, said he was particularly interested in facing Shavkat Rakhmonov (18-0), the unbeaten number-three contender who has finished every opponent so far.

"That fight excites me so much," Garry said. "Shavkat's incredibly talented. I have nothing but respect for the guy... it's purely out of, I don't want
