FIFA has been given more time to present its case to sport's highest court in a fight over whether clubs must release their players for the Beijing Olympics, AP reported. The Court of Arbitration for Sport has allowed the world soccer body until midnight (2200 GMT) Monday _ instead of 9 a.m. (0700 GMT) that morning _ to turn in its paperwork, Schalke and Werder Bremen lawyer Theo Paeffgen told The Associated Press Saturday. The two German clubs and FC Barcelona has filed a joint appeal to CAS, asking it to overrule a FIFA decision that players aged 23 or under must be allowed to play for their country in Beijing. Barcelona wants to keep Argentina's Lionel Messi at home, while the German clubs are fighting to keep Brazil's Rafinha and Diego. Despite the delay, CAS promised on its Web site to issue its ruling by Wednesday _ a day before the Olympic tournament starts.
