Cardiff striker Jimmy-Floyd Hasselbaink has lost an appeal over his sending off in Saturday's 1-1 draw at Colchester.
Hasselbaink is out of Cardiff's next three league games
Hasselbaink was sent off for a 62nd-minute challenge on keeper Dean Gerken, but Bluebirds boss Dave Jones said the incident was "appeal-able".
However, the Football Association of Wales upheld the red card at a hearing on Tuesday.
It means the Dutchman will miss the next three league games starting with the visit of Bristol City on Saturday.
