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

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

“Khamzat Chimaev broke his tooth,” Cormier said of the photo. “He literally dislocated his jaw in two seconds. It was incredible.”

(Warning: UFC 308 photo below is quite graphic.)

Chimaev’s finish marks the first time Whittaker has ever competed in the UFC.

It was a dominant performance from start to finish, as Chimaev nailed a takedown just seconds into the opening round and didn’t give Whittaker a second to catch his breath. Chimaev was dominant but not impatient as he continued to ensure he maintained control of Whittaker as he did his best to scramble free and get back to his feet.

Time and time again, Chimaev pulled him back to the ground as he tried to improve his position.

Once he finally had full control of Whittaker’s back, Chimaev quickly wrapped his arms around the former champion’s face to seal the submission. Chimaev tightened his grip and Whittaker immediately tapped out.

Whittaker apparently told Chimaev in the cage that he had a dislocated jaw, but it wasn’t until he got backstage that the full damage was revealed. It’s clear that Whittaker is headed for oral surgery thanks to Chimaev’s nasty submission.

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