Fifa general secretary Jerome Valcke has called on Luis Suarez to seek treatment after being found guilty of biting an opponent for a third time.
Suarez bit Giorgio Chiellini during Uruguay's 1-0 win over Italy on Tuesday and has been banned from all football-related activity
for four months by world football's governing body.
"He should go for treatment," Valcke said. "It's definitely wrong.
"The first time, it's an incident. More than once, it is not."
International players' union FIFPro called for Suarez to "receive all the support he needs".
"The focus should be on the rehabilitation and serious treatment of the player. FIFPro believes that treatment must be a part of any sanction," a
statement read.
FIFPro said Suarez's prolonged absence from the game "must be addressed as it directly infringes his right to work".
Suarez was banned for 10 matches for
biting Chelsea's Branislav Ivanovic in April 2013 and seven matches for
doing similar to PSV Eindhoven's Otman Bakkal while playing for Ajax in 2010.
"That is why the sanction has to be exemplary," Valke added.
Suarez has received support from World Cup winner Diego Maradona, while Chiellini branded the ban "excessive".
The Uruguayan is not allowed to train with his club or enter a football stadium yet Spanish side
Barcelona remain interested in signing the player from Liverpool.
