Brown gets three-game ban for Neymar kick
Barcelona's Brazilian striker Neymar (L) is challenged by Celtic's Scottish midfielder Scott Brown at Celtic Park in Glasgow on October 1, 2012
Brown was shown a straight red card for bringing the Brazilian down and then kicking out at him during the second half of the Group H game at Celtic Park on October 1, which Barcelona went on to win 1-0.
Brown's dismissal automatically ruled him out of Celtic's home game with Ajax on Tuesday and he will now also miss the return game in Amsterdam and the visit of AC Milan.
"UEFA's Control and Disciplinary Committee has suspended Celtic FC's Scott Brown for the next three UEFA competition matches for which he would otherwise be eligible following his dismissal in the UEFA Champions League matchday two fixture against FC Barcelona in Glasgow," read a statement from European governing body UEFA.
At the time, Celtic manager Neil Lennon described French referee Stephane Lannoy's decision to dismiss Brown as "very soft".
The Scottish champions reacted to the news of Brown's three-match suspension by announcing that he would appeal against it.
