There will be 1,000 empty seats at Hampden Park in November when Rangers and Celtic lock horns for their semi-final clash in the Premier Sports Cup.
Dating back to issues relating to pyrotechnics during last season's semis in the same competition at the national stadium, both sides will be 500 tickets short of their usual allocation after a sanction passed down by the SPFL earlier this year.
The Glasgow rivals will meet on the weekend of November 1/2 after they were drawn to play each other in the final four of this season's tournament. Motherwell will play St Mirren in the other tie.
In March, both Rangers and Celtic were told their next outing in the League Cup at Hampden would see a reduced number of tickets due to pyro displays organised by their respective fan bases during their matches against Motherwell and Aberdeen.
Rangers, Celtic and Motherwell were given a suspended sanction of a reduction of 800 tickets for future Premier Sports Cup matches.
However, both of Glasgow's big two were also handed an immediate 500 deduction, which will come into play when they meet at the start of winter.
The SPFL said: "The SPFL has confirmed that Celtic, Motherwell and Rangers have been found in breach of SPFL rules following separate disciplinary hearings into the behaviour of the clubs’ supporters at this season’s Premier Sports Cup semi-finals and final.
"Proceedings into large-scale, organised and illegal pyrotechnics displays at Celtic v Aberdeen and Rangers v Motherwell in November, and Celtic v Rangers in December, were undertaken by an independent Disciplinary Commission and have now concluded.
"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.
"These displays led to a 14-minute delay to Celtic v Aberdeen, a five-minute delay to Motherwell v Rangers, a 3-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."
