Johnny Walker’s plan to ease into the heavyweight division just got thrown out the window. The UFC fighter accepted a main event spot against Waldo Cortes-Acosta on just nine days’ notice after the original headliner fell through.
Sean Brady and Gabriel Bonfim were supposed to headline UFC Vegas 124 on November 7 at Meta Apex in Las Vegas. Brady pulled out due to a severe staph infection, and the UFC didn’t book a replacement for Bonfim.
That’s when Walker got the call last Thursday after training. He told talkSPORT.com that he wasn’t expecting a fight that quickly but decided to take the opportunity.
Would Johnny Walker fight his brother Valter Walker in the UFC?
"I go in there to hurt other people. I don’t want to hurt my own blood, you know? … Someone who shares your blood, there’s no way. Unless the guy is completely crazy — and I’m not that crazy."

From Slow and Steady to Fast Track
Walker made his heavyweight debut against Mick Parkin in October, winning by first-round knockout and earning a performance bonus. The former light heavyweight had originally planned a different approach to his new weight class.
“I was thinking to take small steps and go slow in the division,” Walker said at media day ahead of UFC Vegas 124. “See how I feel at heavyweight. That was my plan.”
But Walker believes his path has changed for a reason. “God had different plans than me. God has better plans for me,” he said.
The 34-year-old veteran has a record of 23-10 with one no contest. He has competed in 17 UFC fights over his career.
“I’m a veteran now, I’m 34 years old, with a lot of experience,” Walker told talkSPORT.com. “For me, it’s just another day of my life. It’s a normal day for me, so… Let’s go, man. Why not?”
What’s at Stake for Walker
Cortes-Acosta enters the fight ranked No. 8 in the UFC heavyweight division with a record of 17-4. The fighter known as “Salsa Boy” had won three straight fights before losing to Alexander Volkov and Curtis Blaydes this year.
A victory over Cortes-Acosta would launch Walker into the heavyweight Top 10 in just his second appearance in the division. Walker is currently ranked No. 11 in the heavyweight rankings.
The fight represents a quick jump up the ladder for Walker, who knocked out Parkin less than a month ago. Walker said he always stays ready for opportunities like this one.
“The meat fell on the plate of the most carnivore guy and I wanna eat it,” Walker told talkSPORT.com about accepting the short-notice fight.
Mick Maynard, a UFC matchmaker, messaged Walker with the offer last Thursday. Walker accepted immediately despite the short turnaround time.
UFC Vegas 124 takes place Saturday night at the promotion’s Meta Apex facility in Las Vegas. The event will stream on Paramount+.
