Derek McInnes revealed that Kilmarnock will appeal against the red card shown to Lewis Mayo during their 2-2 draw at Dundee.
An early own goal by keeper Will Dennis was cancelled out by Killie’s Marley Watkins.
Luke McCowan then netted from the penalty spot for the home side after Mayo was sent off by referee Colin Steven for his challenge on Scott Tiffoney.
Robbie Deas secured a dramatic draw for Kilmarnock in stoppage time but McInnes was still raging over Mayo’s sending off.
The Rugby Park boss said: “I will appeal (against the decision). Mayo can play against Aberdeen in the cup because it is a different competition.
“He will be suspended for the St Mirren game so we will be appealing it.
“We had to dig ourselves out of a hole after a refereeing decision. I went in to see him. There is no infringement in the box, if there is a foul?
“It’s a bit untidy because Mayo has his eyes on the ball, it bounces and he gets himself in a bad position, but at no time does he pull Scott Tiffoney down.
“Tiffoney falls down and it doesn’t look great. I can’t understand why Greg Aitken and the VAR team haven’t asked the referee to look at it.
“I think if he does, he doesn’t give the penalty and I think it actually makes him think twice as to whether there is a foul there or not.
“If he does get called over and sticks by his decision then we can have a go at the referee. I don’t understand.
“They get involved when they shouldn’t and don’t get involved where they should. I am just scunnered with it.”
Dundee boss Tony Docherty was delighted with the response of his players after their hammering by Celtic last week but he insisted his team should have seen the Killie game out.
He said: “I think the overriding feeling is disappointment.
“We have just had a good discussion as a group. I think the thing I want to emphasise is that we had a difficult night on Wednesday.
“But we won’t be defined by a result like that but what we will be defined by is our reaction to it.
“I thought our reaction today was fantastic but we should have seen the game out.”
