Claudio Sulser, head of Fifa's disciplinary committee, previously stated it would be “disproportionate” to ban Suarez from pre-season training.
However, when asked to clarify these remarks, Fifa insist Sulser was “inaccurate” and that Suarez would not be allowed to train with either Uruguay or Liverpool.
"This is inaccurate," said a Fifa spokesperson. "Claudio Sulser just said he could make the medical testing for a transfer [only this], but clearly said as many times earlier that he cannot do any football activity which includes that he cannot train with the national team nor club."
Suarez is allowed to move clubs during his ban, and Goal understands Barcelona are on the verge of signing the Uruguay international in an €88m deal.
Barca sporting director Andoni Zubizarreta has previously praised Suarez after he finally apologised for biting Giorgio Chiellini during Uruguay's clash with Italy at the World Cup.
Suarez was banned from all football-related activity for four months, suspended for nine competitive international matches and hit with an €80,000 fine for the incident, although Uruguay have appealed the ban in an attempt to get it reduced.
