Violence Sunday erupted in the third quarter when fans invaded the court and hurled smoke bombs during the match between the Belgrade arch-rivals. The score was tied at 43-43.
Because of the clashes, the match was continued without fans on Monday.
Violence at sports events is frequent in Serbia despite new laws that include prison terms for those involved and heavy fines for the clubs.
Similar violence marred the Greek Cup final in Athens on Sunday, forcing the game to be suspended for an hour before Panathinaikos finished off an 81-78 win over arch-rival Olympiakos.
