Celtic will launch an appeal to Uefa after Scott Brown's automatic one-match ban for kicking Barcelona's Neymar was trebled.
Brown was sent off in the Catalan club's 1-0 Champions League victory at Celtic Park on 1 October. The Celtic captain had needlessly kicked out at Neymar after fouling him.
Uefa's control and disciplinary body decided on Thursday to increase the penalty, which would rule Brown out of Celtic's two crucial Champions League meetings with Ajax and the subsequent visit of Milan to Glasgow.
In a statement, Brown's club said: "Celtic can confirm that they have received notification from Uefa of the sanction. The club finds this to be excessive and they will be appealing against the decision."
Brown had received post-match support from his manager, Neil Lennon. The Northern Irishman said at the time: "I think it is very soft. If there was any contact, it was minimal. There was a lot more in a game that warranted heavier punishment.
"I don't think the initial tackle was a severe one. It is a physical game. I don't think Neymar does himself any favours with the way he behaves at times."
The Scotland manager, Gordon Strachan, also stepped into the affair by criticising Neymar's actions.
Brown, however, took on a degree of culpability. "There was not a huge amount of contact at all, to be honest, but I have to accept responsibility for my actions – and I do," said the midfielder.
