KnockOut Promotions lived up to its name on Saturday evening in Grand Rapids, Michigan, at the Deltaplex Arena.
Lightweight Zack Shaw found himself in trouble on the mat against Alexander Trevino, but he quickly turned the tables on his foe and ended the contest.
The announcers were in the midst of discussing the danger Shaw was in when he hoisted Trevino up and slammed him to the canvas.
Trevino was stiff immediately, and the referee saved him from further damage. The violent end moved Shaw to 6-2 in his professional career and gave him a sensational first-round KO victory.
