Midfielder Mark Bresciano is free to play for Australia at the World Cup, the Court of Arbitration for Sport (CAS) has ruled.
The 33-year-old, who has played 73 times for the Socceroos, is currently serving a four-month ban imposed by FIFA.
He began serving the penalty in mid-November, and though he and his club have appealed, the verdict will not be delivered until after he has completed his ban.
The suspension was imposed after a dispute over the transfer compensation fee UAE-based Al-Nasr was due from Qataris Al-Gharafa from his sale in 2012.
The CAS at the weekend rejected Bresciano's application for a stay of proceedings, but decided he would be able to carry on playing in friendlies for club and country. He had been able to play in Australia's 1-0 win over Costa Rica in November despite the ban.
Brendan Schwab, vice-president of worldwide players union FIFPro, said: "Mark is free to play for Australia at the World Cup if selected. The CAS has given careful regard to Mark's interests and in part his desire to play at the World Cup.
"It's decided that his interests are better protected by the stay not being granted and him serving his suspension, as if he were to lose the final decision in March or April then he would be suspended for the World Cup.
"In deciding to appeal, Mark had to take into account the interests of the club and the Socceroos as well as his own. And I expect that the club and Mark will continue the appeal as a matter of principle."
The Socceroos are set to submit their preliminary squad list for the World Cup on 13th May, ahead of the tournament kicking off on 12th June in Brazil.
Australia have been drawn in World Cup Group B alongside European giants Spain and the Netherlands and South American side Chile.
The Socceroos are 1/1 to win Group B, while Spain can be backed at 1/1.
