“That’s automatic CTE” - Fans lose it as 46-year-old Andrei Arlovski flattens reality TV star in boxing debut

Andrei Arlovski turned back time in Nashville, delivering a crushing fourth-round knockout to reality TV star Kelechi 'Kelz' Dyke in his Misfits Boxing debut.

Arlovski, competing in his first boxing bout since retiring from MMA, kept a patient pace early. He measured Kelz with his jab and occasionally tested the guard with single power shots.

By the fourth round, the veteran’s timing caught up with the younger opponent. A sharp right hand landed flush on the chin, sending Kelz collapsing against the ropes before hitting the canvas motionless. The referee waved it off immediately.

Fans reacted in disbelief as clips of the knockout spread online. One fan wrote:

With 42 UFC fights and 23 wins in the promotion, Arlovski is widely regarded as a legend in the sport. He won the interim UFC heavyweight championship in 2005 before being promoted to undisputed champion.

He made his promotional debut in 2000 and went on to script a remarkable career that has spanned four decades. He holds UFC records for most wins and most bouts in the heavyweight division.

Andrei Arlovski talks about his decision to compete in Misfits Boxing

Andrei Arlovski’s late-career move to Misfits Boxing has given him a fresh spark that few expected. The 46-year-old former UFC heavyweight champion stopped reality TV fighter Kelechi 'Kelz' Dyke in the fourth round of his debut in Nashville.

Arlovski has now recorded three straight knockout wins in 2025 across boxing, bare-knuckle, and Dirty Boxing rules. The veteran admitted he only recently learned about Misfits but embraced the chance to compete again. He now has his sights set on bigger boxing names, including Jake Paul.

Speaking in an interview with MMA Fighting’s Damon Martin ahead of the fight against Dyke, he said:

“My manager told me you have an opportunity to fight in a boxing match. Would you like to? I said absolutely, let’s go. That’s how it happened... To be honest with you, shame on me, I never heard about [Misfits]. But right after a little bit, I found out that Tony Ferguson is fighting over there. I guess I’ll find out soon.”
