Kevin O'Brien has had his three match ban for an alleged bite on Donegal's Paddy McBrearty overturned.
The Central Hearings Committee who met last night has found the allegation could not be proven, and the subsequent punishment will not stand.
O’Brien was the subject of the allegations earlier this month in the fixture in Ballybofey where McBrearty needed treatment during the game and afterwards at Letterkenny General Hospital.
O'Brien and the Dublin county board had strenuously denied the allegations and the CHC has now ruled in their favour.
The Dublin players is also now free to play in Sunday's League final with Tyrone at Croke Park.
