Rangers have appealed John Lundstram’s dismissal in Saturday’s 2-2 draw at Hibernian.
The midfielder was shown a straight red card by referee Willie Collum for his tackle on Martin Boyle.
Giovanni van Bronckhorst’s side led 2-1 at the time and were then reduced to nine men when Alfredo Morelos was also shown a straight red and went on to draw 2-2.
As it stands, Lundstram is due to miss Rangers’ next two domestic matches against Ross County on Saturday in the Scottish Premiership then Tuesday’s League Cup tie against Queen of the South.
Rangers, who are understood to be concerned by the haste in which the red card was shown, are thought to be confident in their appeal following Jake Doyle-Hayes’ similar tackle in the match on Lundstram which resulted in a yellow card.
