The red card has been rescinded, that still haven't decided what to do about the game. http://www1.skysports.com/football/news/11912/7392266/Esteban-red-card-rescinded
The fan was already banned from Ajax matches. but a friend got a ticket for him (which is only possible in cup matches).
The game will have to be re-played from the beginning without fans. Ajax also got a 10.000 Euro fine. There were no reprocussions for AZ I think they got of lightly. http://www.shanghaidaily.com/article/article_xinhua.asp?id=42028
