Knockout in main event leads thunderous night at UFC 308

Shara "Bullet" Magomedov (15-0-0) recorded the night's other knockout in the second round of his middleweight bout against Armen Petrosyan (9-4-0).

His was more unorthodox. The talented middleweight spun with his back toward Petrosyan, who blocked his right-handed strike. However, Magomedov quickly turned back and landed a knockout hit with a left backfist.

In the co-main event, Khamzat Chimaev (14-0-0) defeated Robert Whittaker (27-8-0) via a face crank submission. During his post-match interview with Daniel Cormier, Cormier noted Whittaker dislocated his jaw while under Chimaev's choke.

Afterward, in Chimaev's post-match news conference, he expressed sorrow for breaking Whittaker's jaw, albeit with a savage caveat.

"[I feel] bad for that ... didn't mean to [break] somebody's chin. But this is my work, you know. Make somebody pain and make me happy," Chimaev said.

Ahead of the two headliners, Magomed Ankalaev improved to 20-1-1 with a unanimous decision (29-28, 29-28, 29-28) over Aleksandar Rakic (14-5-0). 

Following the win, he called out Alex Pereira (12-2-0) for his next light heavyweight fight. With help from a translator, Ankalaev said, "Alex, stop running away from me." 

Pereira most recently defeated Khalil Rountree (14-6-0) by technical knockout (TKO) at UFC 307 on Oct. 5.

While Ankalaev awaits a potential fight with Pereira, fans won't have to wait long for the next big UFC event.

UFC 309 is scheduled for Nov. 16 and will be headlined by a heavyweight fight between Jon Jones (27-1-0) and Stipe Miocic (20-4).
