Kilmarnock boss Kenny Shiels has revealed his surprise that referee Craig Thomson has not been in touch to apologise for Liam Kelly's red card.
The Killie boss was expecting a phonecall from the match official after claiming his player was wrongly dismissed during Tuesday's 4-0 defeat to Dundee United in the SPL.
Shiels has been left in little doubt about the innocence of Kelly - who was sent-off for a last-man challenge on Gary Mackay-Steven when the game was still goalless - but will not appeal against the decision.
He said: "I'm still waiting on an apology from the referee. He hasn't rung and I thought he might ring to apologise.
"He got the sending-off wrong and that was quite obvious.
"I thought [getting in touch] was protocol but it hasn't happened much to us because we have a really good disciplinary record.
"It mustn't be the protocol but I didn't realise that."
Shiels will not take the case to the Scottish Football Association, claiming the Ayrshire club's appeal would be a waste of money.
He said: "We are not appealing it because I don't think we are a big enough club to win the appeal.
"Case history tells you that I'm losing £1,000 of the club's money so I have declined to appeal it.
"We will just take the medicine - even though we don't feel as though it's just, we are going to take it and get on with it.
"We are disappointed but we carry on. I'm not angry, I'm just frustrated."
Meanwhile, Kilmarnock have been dealt a blow with the news that on-loan Celtic defender Lewis Toshney could be facing a spell on the sidelines with a groin injury.
He is definitely out of this weekend's SPL clash with Hibernian and Shiels is waiting to hear the extent of the injury.
He said: "We've had a bit of bad news. Lewis Toshney has sustained a groin injury in training.
"I don't want to elaborate too much, whether it's a tear or a strain or stress. He's gone to see the physio at Celtic."
