Russian football chiefs have failed in an attempt to suspend the ban on their teams appearing in UEFA competitions.

The Russian Football Union (FUR) lodged an appeal to the Court of Arbitration for Sport (CAS) after its clubs and national team were banned from all FIFA and UEFA competitions "until further notice".

The joint-decision taken by FIFA and UEFA followed Russia's invasion of Ukraine three weeks ago.

Russia "categorically disagreed" with the ban and submitted its appeal, while also seeking an initial stay of execution.

However, CAS, which has yet to announce a schedule for the appeal hearing, has refused to put UEFA's sanctions on hold.

"The challenged decision remains in force and all Russian teams and clubs continue to be suspended from participation in UEFA competitions," CAS said in a statement.

Spartak Moscow were Russia's only remaining representative in European club competition at the time of the decision, with opponents RB Leipzig receiving a bye to the Europa League quarter-finals.

Tuesday's CAS announcement only applies to UEFA competitions. Russia are hoping to overturn a FIFA ban that would potentially allow them to play in the World Cup.

Russia were due to face Poland in a qualifying play-off semi-final later this month, but FIFA instead handed their opponents a bye to the final.

Should Russia fail in their challenge to that ruling, Poland will face either Sweden or the Czech Republic – with that semi-final on March 24 still set to go ahead – for a place at Qatar 2022.

Poland, Sweden and the Czech Republic have each announced they will refuse to play Russia due to ongoing events in Ukraine.
