The SFA have knocked back suggestions referee Bobby Madden has been demoted.
The match official was in the firing line from Celtic fans after he waved away appeals for a late penalty-kick in the 1-1 draw with Rangers at Parkhead on Sunday.
Madden also missed a scissor tackle by Jason Holt on Patrick Roberts which almost led to a Rangers goal and earlier in the match a two footed lunge by Kenny Miller on Stuart Armstrong.
Hoops striker Leigh Griffiths claimed he had been fouled in the box by defender Clint Hill, who later admitted to Brendan Rodgers he “got away with it”.
Hampden bosses have confirmed Madden will take charge of the Dunfermline game against Ayr United in the Championship at East End Park on Saturday.
But claims have been dismissed that the whistler, who was taking charge of the Glasgow derby fixture for the first time, had been taken out of the front line.
One source said: “Fixtures for referees are delivered in four or six week ballots and we’re currently on a six-week rota.
“In that time, category one officials will be given charge of two or three Premiership fixtures, a Championship game and will also be handed duties as a fourth official in a top-flight match.
“It’s incorrect to suggest Madden has been demoted. It was simply his turn to take charge of a Championship fixture this week.”
