Zabit Magomedsharipov has his sights set on UFC featherweight champion Alexander Volkanovski.

With Yair Rodriguez injured and out of their expected Aug. 29 matchup, Magomedsharipov (18-1 MMA, 6-0) and the UFC are in search of a new featherweight opponent.

Wednesday, Magomedsharipov called out Volkanovski (22-9 MMA, 9-0 UFC) in an Instagram post.

“My next fight was supposed to be title eliminator and I won without fighting,” Magomesharipov wrote. “Next is a title shot. @alexvolkanovski I know you’re great champion and you’re tired of fighting Max (Holloway). Let’s try new blood. I promise to make it unforgettable.”

Magomedsharipov also voiced his openness to delaying his return to September or October, should it mean he fights for the title.

“Let’s give fans what they want, if you need a little time September or October fine with me,” Magomedsharipov said.

Earlier in the day, Magomesharipov tweeted a brief challenge to Volkanovski on Twitter. The champion responded, “I am the champ not the replacement fighter but I hope you find a matchup ASAP then chances are I see you later this year.”

Magomedsharipov has not competed since a November unanimous decision victory over Calvin Kattar. Conversely, Volkanovski has fought twice in that time frame, defeating Holloway twice – once by unanimous decision to claim the belt from Holloway and most recently in a tightly contested split decision at UFC 251 in July.
