Rangers have appealed against the red card shown to John Lundstram in Saturday’s 2-2 draw with Hibernian at Easter Road.
The midfielder was sent off for a foul on Martin Boyle just after the hour mark in Edinburgh when the Ibrox side were a goal ahead.
Australian international Boyle was brought down in his own half as Hibs broke away on a counter attack.
Rangers have claimed a wrongful dismissal over the incident.
And it is understood that Rangers have expressed concern regarding the performance of referee Willie Collum in the match to the SPFL.
Colombian forward Alfredo Morelos was also sent off shortly after coming off the bench as the Glasgow side finished with nine men.
A late goal from Josh Campbell was enough to seal a point for the home side as Giovanni van Bronckhorst’s men dropped their first league points of the season.
Following the game, Hibs manager Lee Johnson said he felt Lundstram’s red was “probably a yellow, a tactical foul”, while he has “no idea” whether Morelos would have been sent off if VAR had reviewed it.
Van Bronckhorst admitted his side, who in the middle of a crucial Champions League play-off against PSV Eindhoven, were always going to be up against it after going down to nine men.
“I think John was harsh to get the red card,” he told Sky Sports.
“I think it was a foul but I think he didn’t have any intention to hit him hard so I was surprised he gave the red card. We have to look into it in this one.
“Second red card, I haven’t seen it back. We have to clearly see what happened there. After the two decisions we were with nine men so for us, especially when we had the ball, it was very difficult for us to keep the ball.
“We almost succeeded in getting the three points but in injury time they fell in the right position to score the equaliser.”
