As I remember him getting a red card very recently in a WC qualifier and they said FIFA would decide if he done it on purpose or not As he might either get a 2 or 3 match ban or just 1 and if he gets the former, he will miss Brazil I hope not as I am visiting Arg for the first time next year, just to see Arg play against Brazil I seen it once in real life when both teams came to England but I dont want to remind myself of that match
It was determined by FIFA to be a one game ban leaving him eligible to play against Brazil. If you search Goal.Com or ESPN.Com or Foxsoccer.com you should have no problem finding a story confirming that.
