The K-League Ulsan, where former coach Yoo Sang-cheol spent his days as a player, played the match against Seongnam as a tribute.
They remained undefeated in 9 matches and maintained their lead.
Ulsan players wear uniforms engraved with coach Yoo's name and back number, and gather near the central line with a commemorative message to pray for the rest of the seniors.
Various commemorative banners and placards adorned the stadium, and there was no cheering match for the first six minutes according to coach Yoo's back number.
Ulsan Kim Min-joon scored a header and kissed the tribute armband engraved with coach Yoo's face.
Ulsan, who drew 2-2 at the end of a four-goal slug, continued their unbeaten streak in nine matches, maintaining the lead by four points.
