Jim McCorry is shocked Down defender Conall McGovern's red card has not been overturned but still hopes the player will be cleared in time to face Wexford on Saturday.
McGovern was sent off during the Ulster Championship defeat by Derry on June 7 and has had his plea rejected by the Central Hearings Committee.
With McCorry also revealing that Donal O'Hare, Aidan Carr and Gerard Collins are almost certainly ruled out of Saturday's All-Ireland qualifier with injury, Down are trying to arrange an appeal with the Central Appeals Committee on Friday night.
"We are very, very disappointed with the decision and are looking to take it to the next level," said the Down manager.
"The committee said there was insufficient evidence to overturn the decision of the referee, but I don't know what evidence they were looking at.
"The referee (Eddie Kinsella) said in his report that he had been alerted to the incident by an umpire.
"It's incredibly harsh, because Conall is not even looking at the player (Enda Lynn) and just pushes him away.
"There was no strike so I can't really believe that the red card has been upheld."
Down forward and free-taker Donal O'Hare is a major doubt for the trip to Wexford Park with a calf injury. Aidan Carr has suffered a bad ankle sprain and Gerard Collins has damaged an AC shoulder joint.
"All three are in the very doubtful category but the physio is working hard with them," added McCorry.
