Hull’s appeal against Tom Huddlestone’s sending-off at Everton on Saturday has been rejected by the Football Association, the club have announced.
Huddlestone was shown a straight red card by referee Paul Tierney following his challenge on Idrissa Gueye midway through the second half.
The midfielder will therefore serve a three-match suspension, meaning he will miss the Premier League games against West Ham, Middlesbrough and Manchester City.
Hull were trailing 1-0 when Huddlestone was given his marching orders, and went on to lose 4-0.
The FA’s decision is a blow to their survival hopes with the Tigers currently lying third from bottom, three points from safety.
Huddlestone has appeared in 27 of Hull’s 29 Premier League matches this season, scoring one goal.
