Brendan Allen Targets Christian Leroy Duncan at UFC Vegas 122

Brendan Allen will face Christian Leroy Duncan in the main event of UFC Vegas 122 on Saturday, October 10, 2026, at Meta Apex in Las Vegas, with the middleweights bringing contrasting experience into their five-round contest. Allen aims to extend his three-fight winning streak, while Duncan enters the matchup seeking a sixth consecutive victory and his first UFC main-event win, according to Sherdog.

Allen holds a professional record of 27-7, compared with Duncan's 15-2 mark. The matchup pits Allen's established experience in five-round fights against Duncan, who has never competed beyond the third round of a professional bout, according to Sherdog.

Allen said he welcomes opponents who pursue aggressive exchanges and believes his ability to maintain pressure as a fight progresses could prove decisive. He outlined that approach while discussing Duncan before the event.

"I love guys that want to come kill," Allen said in a pre-fight interview. "But the question with him is, are you willing to be killed? I am.

I'm willing to be killed. That's just how I fight. That's all I know how to do.

When those lights come on, and they say, ‘Are you ready? Are you ready?’ That's all I know how to do is just go try to kill."

The American also contrasted his ability to build momentum during a fight with Duncan's experience in shorter contests. Allen has participated in several bouts scheduled for five rounds, while Duncan has yet to reach a fourth round in his professional career.

"But I build as the fight goes on and he does not build as the fight goes on," Allen added.

Both headliners successfully made weight on Friday, according to MMA Fighting. Allen registered 186 pounds, while Duncan weighed 185 pounds, clearing the middleweight limit ahead of their scheduled main event.

The weigh-ins also produced three weight misses elsewhere on the card. Ismael Bonfim came in at 163.5 pounds, exceeding the lightweight limit by 7.5 pounds for his fight against Francisco Prado, who weighed 155 pounds.

According to MMA Fighting, the UFC confirmed that Bonfim and Prado would proceed at catchweight, with Bonfim forfeiting 25 percent of his purse. Bonfim had previously missed weight by five pounds before a November 2025 bout against Chris Padilla and by 3.5 pounds before a November 2023 fight against Vinc Pichel, which was subsequently rescheduled.

Ketlen Souza also missed weight, registering 117 pounds for her strawweight matchup with Loopy Godinez, who weighed 115.5 pounds. Their bout will proceed at catchweight, with Souza forfeiting 20 percent of her purse.

Brendson Ribeiro weighed 208.5 pounds for his light heavyweight fight against Felipe Franco, who registered 205 pounds. MMA Fighting reported that their contest would also take place at catchweight, with Ribeiro surrendering 20 percent of his purse.

Fili enters with a 25-14 professional record, while Kamaka holds an 18-8-1 record, according to RotoWire. Fili has recorded 10 knockout or technical knockout victories and three submission wins; Kamaka has three knockout or technical knockout victories and one submission win.
