The GAA's Central Competitions Control Committee has proposed a 12-week ban for Diarmuid Connolly.
If the ban were to stick it could potentially rule the star Dublin forward out of action until the All-Ireland semi-finals.
The punishment was announced following the well publicised incident during Dublin's All-Ireland Leinster Senior Championship quarter-final win against Carlow.
Connolly and three Carlow players became involved in a jostling match following a dispute over a line ball at O'Moore Park last Saturday.
As Connolly walked away, as is shown on the video below, the All Star appears to lay a hand on the linesman Ciaran Brannigan.
Under the GAA's Rule 5 - Category 5 Infractions, 5.32 states;
'To interfere with referee, umpire or linesman or sideline official - minor physical interference e.g. laying a hand on, pushing, pulling or jostling, the penalty is a minimum of 12 weeks suspension in all codes and at all levels.'
The Dublin county board will almost certainly appeal the decision and the player would be expected to have his case heard by the Central Hearings Committee.
The referee Sean Hurson opted not to issue a red card at the time and so the case will mostly hang on the referee's match report and whether or not he included the incident.
