During a K League match at Pohang Steel Yard, rocks fell from the ceiling of the spectator stands, injuring one spectator's hand. The Korea Professional Football Federation has urgently requested all K League clubs to conduct safety inspections of stadium facilities in light of this accident. Pohang Steel Yard was sequentially inspecting aging concrete ceilings, but this accident occurred. The league has been conducting 'Major Disaster Prevention Stadium Safety Inspections' since this year and completed inspections on 10 stadiums in the first half of the year. It also plans to conduct inspections on 19 stadiums in the second half.
