Dundee United have made a complaint to the Scottish Premier League over £19,000 of ticket money they claim they have not been paid by Rangers.
United are already demanding £67,000 relating to ticket sales from the Scottish Cup match between the sides and a Scottish Football Association Judicial Panel will rule on the issue in April.
Now, United claim that they had an agreement in place with Duff and Phelps, currently administrators at Rangers, over payment for tickets at the league match at Tannadice on March 17.
A United spokesperson told STV that agreement had not been honoured by the Ibrox club.
He said: "We can confirm that the Administrators in control of Rangers have failed to honour an agreement which was in place and we have not received ticket money due from the game at Tannadice on 17th March.
“The matter is now in the hands of the SPL”
