Quigley was Fermanagh's chief source of scores during the McKenna Cup and National League but rumours abounded in the run in to the Ulster Championship clash with Down that the player had missed training sessions as well as a challenge match.
The Roslea man did feature against the Mournemen as a second half substitute with Fermanagh manager Peter Canavan stating that the player had sustained a hamstring injury a week prior to the game which had ruled him out of starting the contest.
However, the player did not attend training on Tuesday night when the squad met up for the first time since the Down defeat, and Treacy has explained that Quigley has withdrawn from the squad although the door has been left open for the talismanic forward to return in the future.
"I can confirm that Seamus Quigley has left the 2012 Senior Championship panel," said Treacy. "Seamus is no longer in a position to commit to the panel and has therefore withdrawn from the squad. The Management Team would like to thank Seamus for his contribution this year and hope that he will be available to the panel some time in the future."
The draw for the All Ireland Qualifiers will take place tomorrow morning (Monday) at 8.30am.
