Rangers defender Steven Whittaker has called on referee Stuart Dougal to overturn Madjid Bougherra's red card against Aberdeen.
Bougherra was shown a straight red card after sliding in and catching Aberdeen goalkeeper Jamie Langfield in the face during Rangers' 2-1 win at Ibrox.
Rangers are considering appealing the sending off as Bougherra faces missing out on on a potential title-clincher against Dundee United next weekend.
Whittaker has backed Bougherra in his appeal to have the dismissal overturned.
"I passed the ball to Madjid, just tried to slip it through the defence and he made the run around the back," said Whittaker.
"It looked to me as though he was entitled to go for the ball.
"I don't know what the linesman has seen, he was obviously saying that Madjid has followed through. But it looked pretty honest to me.
"It would be (a big blow to lose him). He has been a big player for us, he has been great this season, and hopefully we can get it overturned."
JokeAberdeen full-back Charlie Mulgrew was also controversially sent off in the first half at Ibrox after Kyle Lafferty fell theatrically to the ground as the pair went head to head.
Lafferty could face punishment for his play-acting and Aberdeen star Gary McDonald was scathing over the Rangers player's behaviour.
"It was a joke," McDonald told the club's official website.
"Lafferty should be embarrassed. The TV cameras were there and they will show exactly what he's done. I saw it with my own eyes.
"He just fell over like a big girl's blouse. That's why it's so hard to take, Charlie's season is going to be over.
"Why he has done that I don't know because he's actually the one that went to Charlie initially and then he just fell over. He has to have a look at himself."
