GAA disciplinary chiefs have proposed a suspension for an unnamed Dublin footballer accused of biting Donegal's Paddy McBrearty during the recent Football League game with Donegal at Ballybofey.
The Central Competitions Control Committee have suggested the ban, which is reported to be a three-match suspension.
The Dublin County Board has confirmed that they will appeal the suspension.
McBrearty needed treatment for a cut shoulder, which he sustained in the first half of the drawn match, which consigned Donegal to relegation.
Donegal officials had revealed that referee was informed of the injury and the allegation was mentioned in the referee's report.
Dublin were also made aware of the matter and the Dubs' team doctor was shown McBrearty's injury after the Division 1 game on 7 April.
However, Dublin chairman Andy Kettle said last week that the county's doctor had expressed the opinion that McBrearty's injury looked to be a "bruise, not a laceration".
If the three-match ban does take effect, the Dublin player will miss the Football League Division 1 semi-final against Tyrone and the county's first two Championship games.
McBrearty's shoulder was treated at half-time and following the Ballybofey contest and the Kilcar club-man was then taken to Letterkenny Hospital for a further assessment.
