Cardiff City has raised concerns over the security measures at Swansea City's stadium after substitute Ollie Tanner sustained a leg injury from a collapsing advertising board during goal celebrations following a 1-1 draw. Tanner, who assisted Callum Robinson's equalizer, was injured when fans surged towards the goal, leading to the hoarding's failure. Cardiff's assistant coach Omer Riza questioned the adequacy of security measures to prevent fans from approaching advertising signs, while Swansea's manager Luke Williams acknowledged the need for a review of safety protocols after a similar incident occurred at Crystal Palace just a day prior. Both coaches emphasized the importance of addressing such safety issues to avoid potential injuries in the future. The match also featured chaotic moments, including Erol Bulut's dismissal, which added to the tension of the derby. This incident highlights ongoing concerns regarding stadium safety in Welsh football.
