Down manager James McCartan has confirmed that Aidan Brannigan is definitely out of Sunday's Ulster SFC semi-final against Monaghan.
There will be no appeal against the retrospective ban that the wing back picked up following an incident in Down's quarter-final win over Fermanagh.
Television footage of the match showed Brannigan striking Fermanagh's Marty McGrath in the aftermath of the sending off of Daryl Keenan.
The match officials, including referee Syl Doyle, did not spot the altercation involving Brannigan and McGrath, but the Central Competitions Control Committee have since handed the Down defender a one-match suspension.
That means that McCartan will have to make at least one change to his starting line-up for this weekend's game at the Athletic Grounds.
Speaking about Brannigan's punishment, McCartan told the Irish News: "He got a one-match ban from the last day, retrospectively, so we are missing him. He would be the only person unavailable (from the Fermanagh game).
"Aidan took his punishment. We didn't put in an appeal. It was disappointing from the fact that it was probably something that happened several times in the course of the game.
"But I suppose when you are caught on TV, it is disappointing that, by the letter of the law it is wrong, but it's something that happens regularly on the field of play. But he was man enough to take his punishment."
