An Aberdeen supporter has been jailed for 18 months after throwing part of a stadium seat onto the pitch and seriously injuring footballer Jack MacKenzie. David Gowans, 31, carried out the attack following a Scottish Premiership match between Aberdeen FC and Dundee United FC at Tannadice Park on 17 May 2025. The incident occurred after the final whistle, as supporters entered the pitch following Dundee United’s 2–1 victory, a result that secured them fourth place in the Premiership and qualification for European competition. Gowans threw the broken seat from the stands, striking then Aberdeen defender Jack MacKenzie in the face. The impact caused a deep two-inch laceration to MacKenzie’s left eyebrow and a five-centimetre abrasion beneath his left eye, leaving him with permanent facial scarring. MacKenzie had gone to the area in front of the travelling Aberdeen supporters to applaud them for their backing when he was hit. The defender has since moved on from Aberdeen and now plays for Plymouth Argyle FC. Sentencing Gowans at Dundee Sheriff Court, Sheriff Alastair Carmichael condemned the actions in strong terms. “Your actions were selfish, stupid, dangerous and utterly irresponsible,” he said.“You must have known that by throwing this item, it could hit somebody. If you didn’t consider this possibility, the level of recklessness is staggering.” The case has renewed calls for tougher action against football-related violence, with authorities stressing that such behaviour has no place in the game.
