Swansea City have been unsuccessful in their appeal to overturn Alan Tate's red card against Queens Park Rangers.
The defender was sent off in the first half of the 4-0 defeat at Loftus Road but after reviewing video evidence, the Swans immediately appealed the dismissal.
However, after meeting on Wednesday afternoon, an FAW Disciplinary Panel snubbed his claim of wrongful dismissal.
"The 'Claim' is rejected and Alan Tate is to be suspended with immediate effect for the three (3) match standard punishment," said an FAW statement on Swansea's official website.
Swansea's vice-captain will now miss the New Year's Day visit of Reading, Monday's match at Leicester City and the FA Cup tie at home to League One outfit Colchester on 8th January.
QPR, meanwhile, were successful in their appeal against the red card shown to Clint Hill.
