KHAMZAT CHIMAEV revealed he felt Robert Whittaker's jaw "click" as he appeared to break his jaw before submitting him at UFC 308.

Chimaev, 30, and Whittaker, 33, was a highly-anticipated fight and the co-main event of the night - which ended with Ilia Topuria taking on Max Holloway.

Yet it turned into a lightning quick victory for unbeaten Russian Chimaev as he clinched the win inside the opening round.

After taking Whittaker down, he struck him several times before getting him in a chokehold.

Australian Whittaker immediately tapped out and seemed to instantly clutch his jaw.

UFC commentators reported seconds after the stoppage that Whittaker was thought to have sustained a dislocated or broken jaw.

And Chimaev added to those claims with his post-fight comments.

The now 14-0 star said: "I felt something click in his jaw, I thought it was broken.

"That’s when I knew it was in."

MMA fans were left astonished by Chimaev's finish, with one saying: "HE IS THE REAL DEAL. INCREDIBLE."

While another added: "Literally crushed Whittaker's jaw. About as impressive of a win as it gets..."

A third replied: "His grip strength must be of another dimension ."

And a fourth responded: "We’ve never seen someone like Khamzat."

After his win, Chimaev called for a fight with middleweight champion Dricus du Plessis - who is expected to rematch Sean Strickland early next year.

Chimaev's win over Whittaker is the latest in a line of victories over the likes of Gilbert Burns, Kevin Holland and Kamaru Usman.
