Czech Kickboxer Václav Sivák Embroiled in Controversy Over Pro-Russian Stance
Prague, Czech Republic – Czech welterweight kickboxer Václav Sivák, 26, has ignited a firestorm of criticism after appearing at a press conference ahead of the RFA 29 event wearing a jacket emblazoned with the Russian flag. The display, occurring against the backdrop of Russia’s ongoing military actions in Ukraine, has drawn condemnation from fellow fighters and promoters alike, highlighting the growing political sensitivities within the combat sports world.
Sivák, known for his aggressive fighting style and outspoken personality, has a professional kickboxing record of 35 wins and zero losses, and currently holds the WAKO-PRO World Light Welterweight Championship. He began practicing karate at age six, transitioning to Muay Thai at eleven, and currently trains at Hamr Gym. His amateur record stands at an impressive 94-5.
Outrage from Within the Czech MMA Community
The reaction to Sivák’s display was swift and severe. Ondřej Novotný, co-owner of the prominent Czech MMA promotion Oktagon, publicly denounced the gesture in a strongly worded statement during his “MMA Letem Světem” podcast. According to reports, Novotný expressed his disbelief, stating, “That Russian jacket… What the f***? Is this really necessary?”
Novotný didn’t stop there, criticizing not only Sivák but also Boris Marhanský, the promoter of the Czech-Slovak organization that co-hosted the event, for appearing comfortable alongside Sivák while he displayed the Russian flag. “For me, it’s a disgrace and stupidity. We are in 2026. Either you are completely out of it and don’t realize it… Even if I accept that argument, what I really have a problem with is that you sit with someone on stage, you see they have a Russian flag on their jacket, and you’re okay with that? That says something about you,” Novotný reportedly said.
Several other Czech fighters have reportedly distanced themselves from Russia following the invasion of Ukraine, but Sivák’s public display represents a stark contrast to that sentiment. The incident underscores the complex relationship between sports and politics, particularly in a region directly impacted by geopolitical tensions.
A History of Controversy
This is not the first time Sivák has courted controversy. In 2024, following a boxing match victory over Erkan Murat in Prague, Sivák launched into a profanity-laced tirade directed at the audience after being booed. Reports indicate he shouted obscenities at fans, including a highly offensive and threatening statement. This incident further cemented his reputation as a “bad boy” within the Czech combat sports scene.
Sivák’s aggressive persona and willingness to engage in provocative behavior have undoubtedly contributed to his popularity with some fans, but his latest actions have sparked widespread condemnation and raised questions about his judgment. The incident has also prompted a broader discussion about the responsibility of athletes to consider the political implications of their actions.
Sivák’s Recent Successes and Upcoming Bout
Despite the controversy, Sivák remains a highly successful fighter. In March 2025, he defeated Patrik Záděra by fifth-round knockout to win the vacant RFA K-1 -70 kg championship, although Záděra was ineligible to win the title due to being overweight. He followed that victory with another fifth-round knockout win over Johannes Baas at KO-Warriors 2 in June 2025. Most recently, he defended his title and secured the RFA championship by defeating Yasuhira Kida on points in Bratislava.
Born in Ostrava, Czech Republic, in 1999, Sivák grew up in a Romani locality in Ostrava-Vítkovice. He began training in martial arts at a young age, initially in karate before transitioning to Muay Thai. He joined Hamr Gym at age 16, where he honed his skills under the guidance of Viktor Petrlík, amassing his impressive amateur record.
What’s Next for Václav Sivák?
The immediate fallout from the Russian flag incident remains to be seen. It’s unclear whether Sivák will face any disciplinary action from the RFA or other organizations. However, the controversy has undoubtedly tarnished his image and could potentially impact his future opportunities. His next scheduled bout has not yet been announced, but it is likely to be closely scrutinized given the current climate. Fans and industry observers will be watching to see how Sivák addresses the criticism and whether he will attempt to clarify his position.
The incident serves as a reminder of the increasing intersection between sports and politics, and the responsibility athletes have to be mindful of the messages they convey. As the situation continues to unfold, it will be crucial to monitor the response from the wider combat sports community and the potential consequences for Václav Sivák’s career.
