Rangers have confirmed that they have asked the referee to review the red card given to striker Kenny Miller in Wednesday night’s 7-1 destruction of Dundee United.

The win has seen Rangers go seven points clear at the top of the SPL table ahead of the Old Firm clash on Sunday, in which Celtic are favourites at 5/4 to close the gap, and Walter Smith’s men available at 7/4 and the draw at 5/4.

Miller may well be suspended for the clash after being given his marching orders following a tangle with Darren Dods in the 51st minute, but the Gers have appealed the decision.

After the match, Rangers boss Smith had said: “I had a quick look at it and I didn’t think there was that much in it.

“If it’s violent conduct, it certainly didn’t look like very much at all.”

Rangers are convinced that referee Willie Collum will change his mind over the red card if he looks at the incident again, and if he decides the clash does not merit a red card, the Scottish Football Association’s review panel will have the final say.

Smith is hopeful that the sending off will be overturned as he has admitted the squad is down to the bare bones.

“If Kenny is suspended we are down to 16 players, so it leaves us short,” Smith said.

“We had Sasa Papac and Nacho Novo coming off because of sickness.

“The players we had listed tonight are the only ones available to us.”

Rangers at least have hit a rich vein of form in front of goal with Kris Boyd (6/1 to score the first goal) breaking the all-time SPL scoring record with his five-goal haul at Ibrox last night. The Gers have now bagged 26 goals in their last six league matches.
