Playmaker Peter Whittingham, left-back Andrew Taylor and former QPR attacker Tommy Smith are all available for the visit of the Tractor Boys.
There were concerns that Whittingham could be missing for up to four weeks after he picked up a knee injury in the Millwall victory but he will return as the Bluebirds look to cement their seven-point lead at the top of the npower Championship.
Taylor missed their victory against Birmingham through illness and is ready to come back into the side while Smith came through 40 minutes of a behind-closed-doors friendly with Exeter in midweek having been sidelined since October with a hamstring injury.
Manager Malky Mackay is looking to add one or two players to his squad but will be without former West Ham striker Nicky Maynard for the rest of the season.
