What happened: The Scottish Professional Football League has fined Celtic £7,500 and issued a suspended 1,000-seat reduction at Celtic Park following supporters' pitch invasions during the final day of the Premiership season. The sanctions stem from scenes during the May 16 match against Hearts, where fans stormed the field following a late goal that clinched the club's fifth consecutive league title.

Why it matters: The disciplinary action serves as a final warning for the champions, with the seat reduction penalty remaining active until June 2028 if further 'significant incursions' occur. The ruling comes as Martin O'Neill signs a permanent Celtic contract to lead the club following their domestic double. Police and league officials cited safety concerns for opposing players as a primary driver for the suspended stadium closure.

What to watch: The club must now implement enhanced security protocols at Celtic Park to avoid triggering the seat reduction during the 2026-27 season opener.
