M-1 Challenge 54 & ACB 12 results: Stephan Puetz defends title, McKenzie suffers KO loss

Following an entertaining evening of fights in St. Petersburg, the M-1 Challenge 54 & ACB 12 joint event culminated with Germany's Stephan Puetz retaining his light-heavyweight title with a TKO victory over Valery Myasnikov. Also featured on the card was a co-main event battle for the vacant lightweight title, which saw undefeated Maxim Divnich dispatch Djhambulat Kurbanov to win the vacant lightweight title.

Former UFC fighter Cody McKenzie suffered a KO loss to ACB standout Beslan Isaev in the opening round of their feature fight on the card. It marked Beslan's seventh consecutive win and was one of the few KO losses that McKenzie suffered during his career.

Also worth noting in preliminary action is Russian light heavyweight Artur Astakhov, who is coached by Fedor Emelianenko's longtime trainer, defeated Evgeniy via submission in the third round. He was also the No. 4 light-heavyweight scouting prospect selected by BE's Zane Simon and TP Grant.
