Ipswich midfielder Colin Healy has been ruled out of the visit of Portsmouth.
The Irishman could only manage 40 minutes of the midweek defeat at QPR before going off with a stomach injury.
Former Luton winger Adam Drury replaced Healy at Loftus Road and could be handed a starting berth in a 4-4-2 formation as boss Paul Jewell looks for a return to winning ways.
Captain David Norris is not expected back for another week or so as he recovers from injuries to his ankle and knee.
Goalkeeper Brian Murphy has stepped up his comeback from a broken ankle after coming out of plaster and will be back in around a month, meaning Marton Fulop will continue.
