There’s a good reason why Robert Whittaker tapped out just a split second after Khamzat Chimaev applied a devastating face crank end their fight at UFC 308.

Following the pay-per-view broadcast, Daniel Cormier showed off a gruesome photo that Whittaker sent him showing off the damage done from Chimaev’s jaw-crushing submission.

“Khamzat Chimaev broke his tooth,” Cormier said about the photo. “Literally dislocated his jaw in a matter of two seconds. It was unbelievable.”

Chimaev’s finish is the first time that Whittaker has ever been submitted in the UFC.

It was a dominant performance from start to finish as Chimaev landed a takedown just seconds into the opening round and he never gave Whittaker a second to breathe. Chimaev was dominant but not impatient as he continued to ensure he maintained control over Whittaker as he did his best to scramble free and get back to his feet.

Again and again, Chimaev kept pulling him back down to the ground while looking to advance his position.

When he finally had full control on Whittaker’s back, Chimaev quickly secured his arms around the former champion’s face to lock up the submission. Chimaev tightened his grip and Whittaker immediately tapped out.

Whittaker apparently told Chimaev in the cage that he suffered a dislocated jaw but it wasn’t until after he got backstage that the full damage was revealed. Obviously, Whittaker will be headed for oral surgery thanks to the nasty submission applied by Chimaev.

The win moved Chiamev to 14-0 in his career and 8-0 in the UFC as he takes another step towards a potential title fight in the middleweight division.
