It’s been a full two decades since he won the UFC’s heavyweight championship, but Andrei Arlovski is still going strong, and having a very good 2025.
After picking up finishes in the Dirty Boxing Championship and then bare-knuckle boxing under the BKFC banner earlier this year, Arlovski, 46, scored his third victory of 2025 under the Misfits Boxing banner on Sunday.
Paired up against social media celeb Kelechi ‘Kelz’ Dyke, who was just a kid when Arlovski claimed UFC gold, the heavyweight got the job done in the fourth and final round. “The Pitbull flatlines Kelz in the final round! Andrei Arlovski still has dynamite power,” was the call on the DAZN broadcast.
A deadly right hand felled Kelz, leaving no doubt as to the winner. A six foot six 27-year old, Kelz was 1-1 as a boxer prior to the Misfits Duel: Cracra vs Fox card in Nashville, Tennessee.

Andrei Arlovski defeated Tim Sylvia in February of 2005 to claim an interim heavyweight title in the UFC, defended it, was promoted to undisputed champ, and then defended that title that October. He’d end up losing the belt, to Sylvia of all people, and eventually left the UFC to fight Fedor Emelianenko – the start of a rocky four-fight skid.
After turning things around, he returned to the UFC in 2014 and was a staple of the heavyweight division until last year, when he was let go off another four-fight skid.
At 46, however, Arlovski clearly remains dangerous.
