Russia have failed in their bid to delay their suspension from the World Cup pending the outcome of an appeal to the Court of Arbitration for Sport.

The Russian Football Union had requested that the sanctions imposed by world governing body FIFA over the invasion of Ukraine be stayed until the CAS proceedings were complete, but CAS announced on Friday that the RFU's request had been rejected.

The decision almost certainly means Russia cannot feature at the World Cup in Qatar later this year. They had been in a four-team play-off path also featuring Poland, Sweden and the Czech Republic with the semi-finals and final being played later this month.

Poland, who had originally been due to play Russia in a play-off semi-final, have been granted a bye to the final where they will face either Sweden or the Czech Republic on 29 March.

A statement from CAS on Friday confirmed FIFA's suspension would remain in force, which bans Russian national teams or clubs from any FIFA competition until further notice.

It concluded: "The CAS arbitration proceedings continue. A panel of arbitrators is currently being constituted and the parties are exchanging written submissions. No hearing has been fixed yet."

An appeal to stay a similar suspension imposed by UEFA was rejected earlier this week.

Poland, Sweden and the Czech Republic sent a joint letter to FIFA at the end of last month saying they would refuse to face Russia in the play-offs.

FIFA initially stopped short of an outright ban, and on 27 February said a Russian team could compete on neutral territory as the 'Football Union of Russia', which was again rejected by the three national associations.

The following day FIFA and UEFA jointly announced the suspension of Russia from their competitions.
