Town have decided not to appeal against Grant Leadbitter's red card during yesterday's 1-0 home defeat to Nottingham Forest.
The former Sunderland man was dismissed in the closing stages for a studs-up challenge on Forest midfielder Paul Anderson.
Leadbitter, 24, will miss the FA Cup tie at Chelsea on Sunday, the first leg of the Carling Cup semi-final at home to Arsenal and the league match at Millwall.
The sending off means the Blues will be short of midfielders for the two cup ties with Town's loan players also unavailable.
