Derrytresk will be banned from Ulster and All-Ireland competition for five years after Sunday's All-Ireland final.
The Tyrone club appealed against eight player bans handed out following the violence in the All-Ireland Junior semi-final against Dromid Pearses.
Joe McKee's eight-week ban is overturned while the bans of Kevin Campbell, Michael Robinson, Sean Slater and Brian Gavin are all cut to a month.
The latter four will still be ruled out of Sunday's All-Ireland Final.
The other three unnamed players who received suspensions did not appeal against their bans and will miss Sunday's decider against Galway club Clonbur at Croke Park.
Derrytresk's fine of 5,000 euro has also been reduced to 2,500 euro.
McKee's availability is a major boost for Derrytresk and he is regarded as their most influential forward.
The GAA's Central Hearing Committee has also imposed further sanctions which will apply in Sunday's All-Ireland decider.
Only their team manager, club secretary, team doctor and physio will be allowed to enter the pitch on Sunday before, during and after the game at Croke Park.
In addition, only their team manager will be permitted to patrol the sideline during the game.
Derrytresk will also not be allowed to have their own water carriers during Sunday's game with the GAA's Central Competitions Control Committee instead appointing people to undertake the role.
The Tyrone club has two further appeal options of either making a further plea to Croke Park or heading to the Disputes Resolution Committee and BBC Sport understands that they are certain to exercise one or both of these options before Sunday's decider.
Earlier this week, it already emerged that a female Derrytresk supporter who allegedly hit Dromid Pearses player and Kerry star Declan O'Sullivan with a handbag has been banned from attending GAA games for a year.
Three Dromid players who also received bans are also expected to have appeals heard by the GAA's Central Hearing Committee in the near future.
Dromid were handed a 2,000 euro sanction arising the incidents in the game.
