Boxer lands first-round KO of the year with devastating, snapping left hook

Someone is going to need to scrape him off the mat.

We've seen plenty of solid boxing knockouts already this year, but Murat Gassiev's nasty left hook in the first round of his bout against Jordan Shimmel might just be the best we've seen.

With just 12 seconds remaining in the round, Gassiev backed his opponent toward the ropes, tossed a short overhand right and snapped a left hook that crumbled Shimmel's knees. Absolutely devastating.
