FIFA expect a judge to deliver a verdict in the club-versus-country row surrounding call-ups for the Olympic Games on Tuesday.Werder Bremen and Schalke last week both filed official complaints with the Court of Arbitration for Sport after players from both clubs - Werder's Diego and Schalke's Rafinha - left without permission in order to join up with Brazil's Olympic team.

CAS put the cases on stand-by as FIFA's own appeals process has not yet been exhausted.

"We can confirm that, at the request of various parties (clubs and member associations), the Single Judge of the Players' Status Committee will pass a decision on the obligation for clubs to release their players for the men's Olympic Football Tournament Beijing 2008 in due course, most probably on Tuesday 29 July," FIFA said in a statement.

"The relevant decision will then be notified to the interested parties within very short notice."

Should the decision go against the clubs, CAS will then be asked to make a decision.

Time pressure is an obvious factor with less than two weeks before the football tournament gets under way in Beijing on August 7.
