Video: Murthel Groenhart says GLORY 34 Holzken rematch "ends in a knockout"

Murthel Groenhart and welterweight champion Nieky Holzken are bitter rivals.

They have fought twice before, with Holzken winning decisions both times. But both decisions are strongly disputed by Groenhart, who maintains that he has twice been cheated by the judges.

On Friday night at GLORY 34 DENVER they will fight their trilogy match. Groenhart says that this time he's leaving nothing to chance, and that he's going in there to score a knockout so that there can be no debate about the result.

GLORY 34 DENVER airs live on ESPN 3 from midnight ET/9pm PT and re-airs on ESPN 2 on Sunday night at 9pm ET.
