FIFA did not uphold his ban, the Court of Arbitration for Sport did. They said FIFA's punishment on him was too harsh, and that the 4 month ban will stand, but only for competitive football activities. He is allowed to play in both club and national friendlies, allowed to train and be revealed at the Camp Nou, and allowed to participate in fundraising football events.
suarez and his agent appealed against the ban and fifa allowed suarez to train with barca but not play.
