Referee Dougie McDonald remains convinced that Celtic midfielder Aiden McGeady deserved his second yellow card for diving during the Hoops' 1-0 win over Hibernian at Easter Road.
The game's flashpoint came when the Republic of Ireland player, booked in the first half for a foul on Derek Riordan, was sent off by McDonald after he went to ground following a challenge by Hibs defender Paul Hanlon.
Parkhead manager Tony Mowbray raged at the decision and claimed assistant Gary Sweeney had flagged to indicate a free-kick to the visitors.
McDonald admitted Sweeney's flag was raised for a Celtic foul but claims he over-ruled his linesman because he was in a better position.
The official reportedly held a post-match debrief with the SFA's Head of Referee Development Hugh Dallas, who is backing McDonald's decision.
"Hugh has spoken with Dougie and they are absolutely satisfied the correct decision was taken at that moment in the match,'' an SFA spokesman told the Daily Record.
"The referee was very well positioned at the incident, although the assistant did flag because he felt the Celtic player had been fouled.
"Any action of any player that is designed to deceive the referee is a cautionable offence, no matter where on the pitch it happens.
"It was in that context the yellow card was shown.''
