Celtic and Rangers have both been ordered to play their next home Scottish Cup match behind closed doors after trouble marred a quarter-final tie between the Old Firm clubs at Ibrox.
The punishment follows a Scottish Football Association disciplinary hearing into Celtic's win over Rangers in March, which saw dozens of arrests after clashes on the pitch.
Rangers fans charged on to the pitch to confront Celtic supporters who had spilt on to the playing area to celebrate their team's penalty shoot-out success, and police at the time described the scenes as "shameful".
The clubs will also have to pay their next Scottish Cup opponents £100,000 in compensation for the loss of shared gate receipts.
They have also been warned that any repeat of crowd trouble at Scottish Cup ties in the next two seasons would prompt another closed-door punishment.
Both clubs admitted charges relating to unacceptable conduct from supporters.
An independent review into the scenes previously concluded that "crushing" and "life-threatening violence" were narrowly avoided.
Celtic said the punishment was "disproportionate" following a "relatively small incursion" by its supporters.
A statement from the club said: "Our club has never defended supporters entering the field of play, and we have repeatedly taken action when it occurs.
"However, we understand the part emotion plays in football and would have expected the context and distinction in behaviours to have been taken into account by the panel. Another important distinction is that, on this occasion, Celtic were not the home club, responsible for stadium safety arrangements.
"We will study the panel's report and reasoning when it is available, and will thereafter consider our next steps."
