The three clubs were the subject of proceedings undertaken by an independent disciplinary commission following “large-scale, organised and illegal pyrotechnics displays” at the Celtic v Aberdeen and Rangers v Motherwell semi-finals in November, and the final between Celtic and Rangers in December.

Celtic and Rangers have been hit with “an immediate reduction of 500 tickets for the next Premier Sports Cup match to be played at Hampden Park” as a result of their rule breach at the final.

As a result of their supporters’ semi-final indiscretions, the Glasgow pair and Motherwell were all given “a suspended sanction of a reduction of 800 tickets for a future Premier Sports Cup match to be played at Hampden Park in the event of another breach of SPFL rule H34 through pyrotechnic use by supporters of the club in any SPFL competition before 30 March 2027”.

A statement issued by the SPFL on Wednesday evening read: “All three clubs have been found to have breached SPFL rule H34 in failing to ensure, as far as is reasonably practicable, that their supporters did not engage in ‘unacceptable conduct’ at those matches.

“The clubs were also found to have failed to identify or take proportionate disciplinary measures against the supporters responsible for the pyrotechnic displays.

“The displays led to a 14-minute delay to Celtic v Aberdeen, a five-minute delay to Motherwell v Rangers, a three-minute delay to the Premier Sports Cup final, a health and safety risk to fellow supporters, players and those working at matches, as well as a significant inconvenience to thousands of supporters at the matches and fans watching worldwide.”
