I pulled this from the CBC website:
It is the third biting incident involving the talented but controversial striker.
Suarez was banned for seven matches by the Netherlands football federation in 2010 after biting PSV Eindhoven player Otman Bakkal in a league match when he played for Ajax.
After moving to Liverpool, he bit Chelsea's Branislav Ivanovic in 2013 and was banned for 10 games.
FIFA can sanction players with bans of up to two years if its disciplinary commission decides there is a case to answer.
