The Scottish Professional Football League is unlikely to take action against Celtic and Rangers over the behaviour of their fans at the recent League Cup semi-final.
Twelve supporters were arrested for alleged sectarian offences at the game.
But the SPFL say both clubs did all they could to avoid any offensive behaviour in the match at Hampden.
And they revealed, as yet, there is no evidence of any breaches to the SPFL's rules by Celtic or Rangers.
A spokesman for the SPFL said: "Official reports from the match are still awaited.
"However, it is clear from information already received that all parties prepared properly and thoroughly for the match and, to date, we have not seen any evidence of any breach of SPFL rules by either club."
Celtic ran out 2-0 winners in the game, courtesy of goals from Leigh Griffiths and Kris Commons, to set up a League Cup final meeting with Dundee United.
