Dundee United have launched an appeal against the red card shown to Tony Watt in the weekend defeat to Motherwell.
The striker was dismissed for a tackle on Sean Goss at the halfway line during the 1-0 loss at Tannadice on Saturday.
Referee John Beaton initially played on but decided to send Watt off after consulting the VAR monitor in the Premiership clash.
Sondre Solholm proved to be the match-winner after his 22nd-minute header was palmed over the line by recalled goalkeeper Mark Birighitti.
The SFA has now confirmed that a wrongful dismissal claim has been launched against the red card that was shown for serious foul play.
A fast-tracked hearing will take place on Wednesday.
Liam Fox cast doubt on the decision in his pre-match interview saying there would have been a different outcome if the ref was shown the incident from another angle.
He said: “Having seen the footage that the referee and the VAR has seen I could probably say, yes, it is a red card.
“But I have also seen other footage from different sources that maybe cast a wee bit of doubt over it so it is a bit of a contentious issue.
“It was a different angle and I see Tony is pulling his leg back and there is very, very little contact with the player.
“I am frustrated at that and frustrated that we started the game well and then had a wee spell where we kind of lost our way a wee bit and then lost the player.
“But what I can say, and say this honestly, if I get what I got from the players in the second half attitude wise, application and bravery in possession, then we will be okay.”
