The season's week 25 derby match, pitting reigning league champions Hajduk versus current league leaders Red Star, on 4 May 1980 at Poljud Stadium in Split was abandoned in the 41st minute due to the announcement of the death of Marshal Tito that was followed by a mass display of public grief within the stadium by fans and players alike.
Played on a Sunday afternoon, the televised contest was in the 41st minute when three men entered the pitch, signalling to the referee—Husref Muharemagić of Janja—to stop the match and gather players of both teams in the centre circle.
With the contest halted, Split mayor Ante Skataretiko [sh] took to the stadium's public address system to formally announce to the 50,000+ crowd that the Yugoslav lifetime president Josip Broz Tito had died.
The Yugoslav Football Association (FSJ) declared the match null and void, ordering a replay for Wednesday, 21 May 1980 at the same venue.
