Super middleweight Christian Mbilli (29-0, 24 KOs) looked powerful with a lightning-quick first-round knockout win over Maciej Sulecki (33-4, 13 KOs) to claim the WBC interim 168-lb title in the main event on Friday night at the Centre Videotron in Quebec City, Canada
Mbilli stalked Sulecki, 36, around the entire round, finally trapping him against the ropes. He then landed a left and a right to the body and a right uppercut that put him down. Although Sulecki got to his feet, referee Michael Griffin halted the contest when the Polish fighter staggered while being checked.
In the chief support bout, super middleweight Steven Butler (36-5-1, 30 KOs) destroyed journeyman Jose de Jesus Macias (29-14-4, 15 KOs) by a fourth round of a scheduled 10-round bout. The first three rounds were back and forth with both guys landing bombs.
In the fourth, Butler, 29, connected with a clean right hand to the head of Macias, dropping him hard. When he got to his feet, he looked hurt. Seeing that Macias was defenseless, Butler went into theatrical mode, winding his right before landing a big shot that dropped Macias. The referee halted the fight at that point. The time of the stoppage was at 1:33 of round four.
Heavyweight Arslanbek Makhmudov (20-2, 19 KOs) looked powerful, bludgeoning the hapless Ricardo Brown (12-1, 11 KOs), knocking him out in the first round. Makhmudov trapped Browne in the corner, then teed off on him with a series of clubbing shots that sent him down face-first into the canvas. The time of the stoppage was at 1:57 of round one.
