Uefa have deemed his action in the game against Barcelona 'assault,' which would raise a few eyebrows in some Glasgow hostelries on a Friday night.
It doesn't matter how much force actually impacted on Neymar's arm, Scott has been done for intent.
You have to admit, the more you look at what he did - and Uefa have had over a fortnight to study the footage - the more stupid it becomes.
They want to put down a marker against this kind of behaviour, and you can argue they have made an example of Scott.
Celtic have said they will appeal, but that runs the risk of ruling him out for even longer, which would mean Scott missing the remainder of the group stage campaign.
I really don't think it's worth taking that gamble, especially given Celtic's records in appeals with Uefa.
I go back all the way to the Rapid Vienna case in 1984 when we were found to be in the clear, then ended up having to replay the tie at a neutral venue.
We couldn't even contest that decision - because it had been made on appeal and you couldn't appeal an appeal.
So, I'd steer well clear of going back with this one in case it ends up with Scott receiving a bigger punishment and it becomes a distraction to everyone else trying to get Celtic's Champions League campaign back on track.
Scott will know he made a big mistake. No-one will have had to say anything to him about what he did.
He would have felt isolated when he got back to the dressing room after receiving his red card, and will feel even worse when the team walks out without him on Tuesday.
Be sure, Scott will be a big, big loss to the team because he has been so important as a leader.
You saw that again when he drove Scotland to the excellent win over Croatia. He's just in that place in his career at the moment.
Who can Neil Lennon ask to fill his boots? There are plenty of candidates to take over the armband, but is there really anyone who can lead the team the way Scott does, more by his performance than his shouting?
The rest of the players will feel they can win without him, but they will all know they would have had a better chance if he was there.
It's a pity Joe Ledley is only just returning to training after so long out as he would have been a natural replacement.
Can Beram Kayal step forward to fill the void? He will feel he should have played more often, but now, if called, he has the best possible opportunity to prove that point.
It's a pivotal night in the group, and, while Neil has said it is a game they must not lose, I believe it is a game they must win, for psychological reasons, if nothing else.
Celtic have no points after the opening two games, and will only have one more at Celtic Park after this one, so they need to get all three points before they head to Amsterdam.
If they can get four points from these back-to-back games, and Milan take nothing in their double-header against Barcelona, it will be all to play for again in terms of second place when the Italians come to Glasgow on matchday five.
Ajax boss, Frank de Boer, will be happy to leave Glasgow with a point as he will fancy his side to win at home, where they were unlucky not to take all three points against AC Milan at the start of this month.
Even without Scott, I don't think Celtic will be too intimidated going to the magnificent AmsterdamArena.
The clubs have enjoyed some wonderful battles over the years. But, it's fair to say, neither is operating at the level they were when the Celtic team I played in faced Johan Cruyff, Ruud Krol, Johan Neeskens and Co in the European Cup quarter-final in 1971.
The first leg was in the Olympic Stadium in Amsterdam, and I was detailed by Jock Stein to mark the magnificent Johan.
I was doing okay, as was the entire team, for the first hour. Then, bang, they stepped it up and scored three goals to leave us with a mountain to climb in the return leg.
We won 1-0, with a first-half goal from wee Jinky, but, in truth, never looked like getting near bringing the tie level.
Ajax went on to win the European Cup that year and the two after that as they dominated Europe.
No-one really expects either Celtic or Ajax to be contesting this season's Champions League final in Lisbon, but both clubs will still believe they can at least reach the last 16.
Whoever wins on Tuesday will have done their chances of achieving this a world of good, and Neil has a few big decisions to make ahead of the game.
He will hope Mikael Lustig recovers from the hip/groin problem because his availability can open up a lot of options.
It's Sod's Law Adam Matthews is already out if Mikael fails to make it and it's too big a game to think about gambling with young Darnell Fisher, good though he looked in pre-season.
This is a time for experienced men to put in an experienced performance.
