FK Sloga Doboj pulled off a notable cup upset, defeating top-flight side FK Zeljeznicar 1-0 away from home in the Bosnia and Herzegovina Cup on February 25, 2026. The match, with a late 11:00 PM kick-off, was decided by a solitary goal from the visiting team, who defended resolutely throughout to protect their lead. Zeljeznicar, fresh from a big win in the previous round, struggled to break down a well-organized Sloga Doboj defense and were punished for their lack of cutting edge. This result stands as a major highlight in Sloga Doboj's season, knocking out one of the tournament favorites and earning them a place in the next round. For Zeljeznicar, the shock exit is a significant disappointment, ending their cup ambitions earlier than anticipated.
