The Scottish champions discovered the punishment handed down to McCoist by the Scottish Football Association ahead of tonight's goalless draw against PSV Eindhoven.

The Ibrox number two and Celtic boss Neil Lennon were both charged with misconduct following their clash after the final whistle of last week's Scottish Cup tie between the Old Firm rivals.

The sanctions mean that McCoist will be banned from the touchline when Rangers face Celtic again in the Co-operative Insurance Cup final on March 20.

Asked whether Rangers plan to appeal, Smith said: "We don't know. We only found out before the game so we haven't had a chance to sit down and talk about it.

"Obviously we are disappointed that the thing happened, that's something that happens. Its a two-match ban and he will have to sit out a couple of games, basically that's it."

Madjid Bougherra and El-Hadji Diouf, who were both shown red cards in the Scottish Cup tie, have also been reported to the SFA's disciplinary committee for "misconduct of a significantly serious nature".

Smith added: "It's a concern that it happened, never mind that we have injuries or anything like that.

"We have already stated that we are a little bit disappointed by their actions so we will just have to wait and see what happens."

Smith sprang a surprise when he handed a starting role to Neil Alexander, with regular first choice goalkeeper Allan McGregor named on the bench.

And the move paid off as Rangers earned a goalless draw in Holland tonight that gives them a fighting chance of progressing to the last eight of the Europa League.

Smith said: "He handled it very well. Coming into the final stages of season, we need to make sure both keepers are match fit and have the required sharpness.

"He played very well tonight, as he has done any time we ask him to play."

Smith added: "We are very pleased with the result. We expected the type of game we got. We knew we would have to defend very well and we managed to do so.

"We are very pleased with the outcome. We had one or two bits of luck and there were one or two poor finishes but overall we were excellent in terms of restricting PSV's opportunities. We've got to be happy with the outcome tonight."

But he warned that Rangers face another difficult night in Glasgow in next week's second leg.

He said: "In the second leg, a lot depends on circumstances of the match. We will have to do more attacking.

"For them the away goal is a big thing. We will approach the game with the same care and levels of concentration as we did this one. PSV will be as dangerous, if not more so, at Ibrox."
