Teenage striker Connor Wickham missed the 4-1 defeat at Swansea on Monday with a rib injury and is out while on-loan Hull midfielder Jimmy Bullard is unlikely to be fit after a recurrence of his long-standing knee problem.
Captain Gareth McAuley had to be replaced during the second-half with a groin strain and is out while on-loan Celtic defender Darren O'Dea has played his last game for the club.
O'Dea picked up an ankle injury on Monday and is out for the rest of the season so Mark Kennedy will return at left-back.
Striker Tamas Priskin is back at Portman Road after a knee injury ended his loan spell with Swansea but he will not feature again this season.
