Rangers are challenging the two-match suspension for Sone Aluko proposed by the Scottish Football Association for simulation.
On Thursday, a fast track tribunal will determine if Dunfermline boss Jim McIntyre was right to say Aluko dived to win a penalty on Saturday.
Rangers say the newly-signed midfielder was adamant he had been fouled.
McIntyre is also in hot water, with a hearing set for 22 December to examine his criticism of referee Steve Conroy.
Conroy pointed to the penalty spot when Aluko went down, with the home side leading 1-0.
Nikica Jelavic netted the penalty but Joe Cardle pulled one back for Dunfermline to set up a tense second half.
After the game at Ibrox McIntyre criticised Conroy, saying: "For the second goal, the ref has had a nightmare.
"I've just watched it on video and it was never a penalty. It was a really, really poor decision."
Aluko later replied: "I felt there was contact and then I fell over.
"I'm not one who normally dives. I thought it was a penalty and obviously the ref did as well."
The same punishment was offered to Hibernian striker Garry O'Connor in October, after he was accused of having dived to win a penalty during his team's 3-2 win over St Johnstone, with Conroy the referee on that occasion also.
O'Connor chose to contest the decision, which was referred to a fast-track tribunal, who upheld the referee's original decision.
If Aluko is found guilty of diving at Thursday's hearing, he will miss Scottish Premier League matches against Hibernian and Inverness.
