The Swiss club were thrown out of the tournament on September 2 after being found guilty of fielding ineligible players, with Celtic handed their place in the group stages despite losing the play-offs 3-1 on aggregate.

Sion vowed to fight their expulsion but have lost their appeal to be reinstated following today's hearing.

A UEFA statement confirmed: "THE UEFA Appeals Body today rejected FC Sion's appeal against their expulsion from the group stages of this season's Europa League."
