At the Immun Fight Club event, a shocking moment unfolded when Juuso Renfors delivered a brutal technical knockout to Markus Rytöhonga in the evening's second match. Renfors struck Rytöhonga down to the canvas twice, prompting the referee to step in and stop the fight. Initially, Renfors landed a punch to Rytöhonga's stomach, and after the count, he followed up with another kick to the same area, leading to the referee's intervention as it became clear Rytöhonga could not continue.

This situation stirred significant concern, particularly voiced by Iltalehdi’s combat sports expert Jaakko Dahlbacka, who expressed his discomfort at witnessing a retired fighter in such a vulnerable position. He noted that Rytöhonga had previously retired and, in his opinion, should not have been in a position to be knocked out in a fight. Dahlbacka suggested that such retired fighters might find safer avenues in grappling or jujitsu competitions instead of engaging in knockout-oriented events where their health could be at serious risk.

The incident highlights ongoing discussions about fighter safety, especially concerning athletes who have stepped away from competitive fighting. Experts like Dahlbacka advocate for more stringent considerations regarding the participation of retired fighters in potentially dangerous situations, emphasizing their health and family responsibilities. Although no serious harm occurred during the bout, the implications of allowing retired fighters back into the ring remain a topic of debate within the combat sports community.
