Václav Mikulášek Exposes RFA Champion Václav Sivák’s Payouts
Former Oktagon MMA fighter Václav Mikulášek has publicly mocked RFA champion Václav Sivák over his fight earnings, claiming he has direct knowledge that the undefeated striker once pocketed just 3,000 euros for a championship bout. According to reporting from fights.cz, Mikulášek stated on Instagram that Sivák’s historical payouts never exceeded his own career earnings. He cited information allegedly obtained directly from RFA promoter Boris Marhanský while Mikulášek was still under contract with Oktagon.
Press Conference Confrontation at Tipos Arena Preview
The war of words spilled over into physical confrontation during the opening press conference for Fight Night Challenge 12, held on Thursday, October 8, as reported by Ruik. Sourced accounts from Tiscali.cz note that after Sivák threatened to break Mikulášek’s ribs within the opening two rounds of their upcoming bout, Mikulášek stepped forward and challenged him to a wager.
Sivák attempted to shove his heavier opponent, but the weight disparity proved decisive. Mikulášek stood his ground while Sivák staggered backward. Security personnel intervened to separate the fighters before Sivák could land a follow-up kick, as detailed by MMA Shorties.
Weighing the Disparities in the Ring
The December 12 bout at Bratislava’s Tipos Arena pits two fighters from vastly different natural weight classes against one another under boxing rules with a 95-kilogram limit, as outlined by Centrum.cz.
While Sivák typically competes around 70 kilograms and enters the contest on a pristine professional run, Mikulášek spent the bulk of his MMA career fighting at middleweight (up to 84 kilograms) before claiming a Clash of the Stars title against Karlos Benda in June. Sivák acknowledged in interviews cited by Tiscali.cz that Mikulášek holds approximately a 20-kilogram weight advantage, dismissing the MMA veteran as a boxing beginner despite acknowledging the physical demands of the matchup.
Tight Schedules Before the December Clash
Before stepping into the ring with Mikulášek in mid-December, Sivák faces a demanding preliminary test under the RFA banner. Meanwhile, Fight Night Challenge continues to promote the December 12 card via its official digital channels, transforming an unexpected cross-promotional pairing into one of the winter calendar’s most contentious combat sports events.
