The 2010 hurler-of-the-year was a designated water-carrier on the day after only recently returning to training following a three-month hiatus.
GAA rules state water-carriers are not permitted to enter the field of play but Corbett did so on a number of occasions to aid his team-mates on a warm day in Thurles. The fine for the infringement is €400 but a repeat infraction could see the Thurles Sarsfields man banned from the pitch enclosure in that capacity for one or more games.
However, it is unlikely such a potential suspension would not affect him were he to be named in the panel for the Munster semi-final against Cork on June 24.
On Twitter yesterday, Corbett joked about the punishment, posting a photograph of coins with the caption: “Definitely a fundraiser needed in the bar to foot the cost of pitch fines.”
Meanwhile, Monaghan will likely hear from the Central Competitions Control Committee today if Owen Lennon is to face further punishment for an incident involving Michael McCann on Sunday.
As highlighted on The Sunday Game, the midfielder stood on his Antrim opponent as he attempted to follow the play.
Referee Maurice Deegan appeared to have dealt with the matter when he brandished Lennon with a yellow card at the next break in play.
However, there is still the possibility he may face a retrospective suspension.
On Twitter, McCann said Lennon apologised to him following the altercation but questioned the authenticity of his contrition.
Responding to former Laois player Colm Parkinson who spoke about the incident on The Sunday Game, McCann said: “He did (apologise) after the incident but might have been more to avoid the red. Few bruises, that’s championship football.”
A one-match ban would rule Lennon out of Monaghan’s Ulster semi-final clash with either Down or Fermanagh on June 24.
