Rangers and Hibernian have been charged by the Scottish Football Association after fans from both sides invaded the pitch and allegedly caused damage at the end of the William Hill Scottish Cup final.
After Hibs triumphed 3-2 at Hampden Park in May to win the trophy for the first time in 114 years, the post-match celebrations were marred by trouble.
The Glasgow giants and the Edinburgh club have now been issued a notice of complaint by the SFA's compliance officer, who has alleged that supporter misbehaviour led to damage of the stadium.
A statement from the SFA published on Tuesday afternoon claimed the surface of the pitch, a set of goal posts and parts of the LED advertising system had been damaged by Hibs fans.
Rangers supporters also stand accused of damaging advertising equipment and advertising hoardings situated at the perimeter of the pitch.
Both clubs have until the close of business on Tuesday, September 6 to provide written responses to the alleged breaches, with Hibs representatives asked to attend a hearing on October 4.
Rangers' principal hearing has been scheduled for October 5.
The Light Blues have already demanded "urgent" talks with the SFA and the author of a report into the pitch invasion after claiming there were "factual inaccuracies and contradictions" in the document.
The SFA released the 52-page report, written by Edward Bowen, a Sheriff Principal from Lothian and Borders, on the evening before Rangers kicked off the new Ladbrokes Premiership season against Hamilton earlier this month.
In response to a statement issued by the Scottish FA a Hibernian spokesman told Press Association Sport : "The club will respond to the Scottish FA once we have had the chance to study the documentation in detail."
