Norwich have failed with an appeal against goalkeeper Mark Bunn's red card in Sunday's Premier League draw at Sunderland.
The FA regulatory commission have upheld referee Chris Foy's decision to dismiss Bunn after he was ajudged to have handled outside his area in the 30th minute of the 1-1 draw at the Stadium of Light.
Bunn was infuriated by the decision, although replays of the incident showed that the ball appeared to strike his chest and arm as he raced from his box to deny Danny Graham after Michael Turner's poor back-header.
Bunn will serve his one-match suspension when Norwich travel to face Wigan at the DW Stadium on 30 March.
A statement from Norwich read: "An appeal by City against the red card shown to Mark Bunn by referee Chris Foy in the Premier League game away to Sunderland has been rejected by an independent regulatory commission appointed by the FA."
