The Armenian-born, Quebec-based Bazinyan beat Montreal’s Steven Butler by 10th-round technical knockout in the co-feature on the Jhon Orobio-Hendri Cedeno undercard at Casino de Montreal. The sharper, busier Bazinyan landed a right hand that buzzed Butler less than 10 seconds into the final scheduled round and followed up with a barrage of punches that sent Butler to one knee.

Butler got up before the count of 10, but referee Junior Padullo decided he shouldn’t continue. The official time of the stoppage was 22 seconds of the 10th round.

Bazinyan (33-1-1, 24 KOs) became the seventh opponent to beat Butler (38-7-1, 32 KOs) by knockout or technical knockout in his 12-year pro career.

Montreal’s Butler fought for the first time since Edgar Berlanga beat him by seventh-round TKO July 26 at Madison Square Garden’s Infosys Theater in New York. Butler, whose fight with Bazinyan was postponed twice within the last year due to Bazinyan’s injuries, replaced injured Cuban Lenar Perez as Bazinyan’s opponent on barely one week’s notice.

Bazinyan ended a much longer layoff than Butler. He last competed in September 2024, when Jaime Munguia knocked him out in the 10th round at Desert Diamond Arena in Glendale, Arizona.

Prior to the knockout Thursday night, Bazinyan nailed Butler with a left hand that knocked him flat on his back just as bell sounded to end the ninth round. Padullo oddly didn’t count it as a knockdown, but Butler wasn’t fully recovered when the 10th round began.

After buzzing Butler toward the end of the fifth round, Bazyinyan beat up Butler for much of the sixth. He switched to a southpaw stance at times and alternated landing lefts and rights on his vulnerable opponent.

A right hand by Bazinyan wobbled Butler with just under 20 seconds to go in the fifth round. A battered Butler held his way to the end of the round, but that disconcerting sequence signaled what was to come.

Bazinyan attacked Butler’s body throughout a successful fourth round.
