Glory 34 is headlined by a huge rematch from one of the best kickboxing fights of 2015, as Welterweight champion Nieky Holzken again takes on Murthel Groenhart. Holzken is one of the very best fighters in the sport today, and has looked tremendous in Glory, but Groenhart gave him all he could handle a year ago. Many felt Groenhart should have won that decision - he has a chance to take the win he feels belongs to him here. The show also features a quality co-main event, as former Middleweight champion Simon Marcus makes his return from losing the belt, rematching the tough Dustin Jacoby. Rounding out the main card is a Middleweight contender tournament. On the Superfight Series, you have former Lightweight king Robin van Roosmalen dropping down to challenge Gabriel Varga for Varga's Featherweight title, plus the much-anticipated Glory debut of Thongchai Sitsongpeenong, teammate to Lightweight champ Sittichai.
