2015 round of the year: Krzysztof Glowacki-Marco Huck produces memorable sixth round

— -- Poland's Krzysztof Glowacki was an afterthought leading up to the fight.

Although unbeaten, he was also an unknown mandatory challenger and supposedly going to be the answer to a trivia question: Whom did cruiserweight titleholder Marco Huck beat to retain the title for the 15th consecutive time and break the division record for most defenses?

But a funny thing happened on the way to making history on Aug. 14 at the Prudential Center in Newark, New Jersey.

Germany's Huck (38-3-1, 26 KOs) got upset as Glowacki (25-0, 16 KOs) stopped him in shocking fashion in the 11th round to win the title and end a legitimate fight-of-the-year candidate with a knockout-of-the-year candidate as the largely Polish crowd of 5,843 went absolutely wild.

The fight, which was the co-feature of a Spike-televised Premier Boxing Champions card headlined by the heavyweights Steve Cunningham and Antonio Tarver, was terrific from start to violent finish. But no round was more hard-hitting and exciting than the sixth, the 2015 ESPN.com round of the year.

Huck got off to a shaky start to the fight, but by the sixth round he had established control, which he further exerted when, 30 seconds into the round, he nailed Glowacki with an overhand left to the temple that knocked Glowacki flat on his back in the center of the ring. It was first time he had ever been down.
