Suarez left the Uruguay camp in Brazil and returned home to Montevideo after the governing body's disciplinary committee imposed a ban of nine international matches, as well as a lengthy total suspension that will devastate his club's plans for the new Premier League season.
The 27-year-old, dealt with as a serial biting offender by the FIFA panel who took two previous cases into consideration before delivering its verdict on Thursday, intends to appeal the sanctions, though the Uruguayan FA has yet to submit a formal complaint.
A potentially protracted appeal process could delay Liverpool confirming their next move.
Anfield officials are still awaiting full documentation from the disciplinary committee - details which may not be revealed until after the appeal process is concluded - but are understood to have taken specialist legal advice.
FIFA's ruling states that Suarez cannot take part in any football-related activity - including entering any stadia - for the duration of his ban but lawyers are still trying to ascertain the minutae of the case, with ramifications for the forward's training regime still to become clear.
The four-month suspension does not extend to transfers and it is understood neither Barcelona nor Real Madrid have been put off by the latest development in Suarez's controversial career.
Support for Suarez came on Friday from the player he bit in Uruguay's final group fixture - Italy's Giorgio Chiellini.
The Azzurri defender declared the punishment "excessive", while Suarez's lawyer described the ban as "grotesque and absurd".
But while FIFA president Sepp Blatter sidestepped questions on the subject, general secretary Jerome Valcke defended the sanctions - and urged Suarez to seek treatment.
Speaking at FIFA's daily media briefing in Rio de Janeiro, Valcke said: "A message to Luis Suarez? I think he should find a way to stop doing it. I think he shoud go through treatment because it's definitely wrong.
"It's not the first time. If it's the first time, it's an incident. If it's more than one time it's not just an incident and that's why the sanction has to be exemplary."
Responding to Chiellini's criticism of the duration of the ban, he added: "You will always find someone who thinks the punishment is excessive.
"This decision has been made by the disciplinary committee based on what they have seen. It was seen by millions of people and it is not what you want children around the world who are playing football to see. Wherever you are playing football, whatever you are doing in life, this should not happen."
Should he remain at Anfield, Suarez will miss at least 12 club games - nine Premier League matches plus three Champions League games, and potentially a Capital One Cup match too - before a return at the end of October.
Assuming Real Madrid & Barcelona have no interest in signing Suarez; and Man Utd fans have No bias against Suarez or Liverpool. Suarez is banned for 12 club games for Liverpool next season and fined circa 65k? FIFA require clubs to make players available for International matches and are penalising Liverpool for doing so! In Law separation of personality is important; the team Suarez played for whilst committing the offence was the Uruaguay team not the Liverpool team. Liverpool lose access to use an asset (Suarez) that they still have to pay a weekly wage to for the 12 matches. Choices: 1) Accept it 2) Sue Suarez for the loss associated with this ban 3) Appeal the ban Then there is option (4) which is to Sue FIFA! If FIFA lost they may be forced by the courts to compensate Liverpool FC for the 12 match ban they imposed; as Liverpool are contractually obliged to pay wages to Suarez? In addition FIFA have already imposed a fine of circa 65k on Suarez and would be unable to increase the fine imposed on Suarez. However, Liverpool FC must consider any reputational damage the club would receive if they sued FIFA and the likelihood of success in the courts. Based on the evidence so far; I believe FIFA may be exceeding the remit they have by damaging Liverpool's ability to compete in the Premier League and other Cup competitions until October! As for all the Man Utd fans looking for an unfair advantage or with Bias against Liverpool FC. Suarez should be penalised if guilty of biting or committing any other offence. However, in law once an individual has served a punishment for an offence it is not permissible to penalise them for that old offence time and time again! New offences yes; old offences that have been already punished Absolutely not! I'm personally hoping Liverpool FC sue FIFA and put some manners on Sepp Blatter and the Fat Cats!- gyrate
