Ipswich boss Roy Keane will be without Jack Colback and Jake Livermore for the Carling Cup clash with Northampton.
The on-loan duo are cup-tied having appeared in the competition already for parent clubs Sunderland and Tottenham respectively.
Keane is also still without left-backs Mark Kennedy (hamstring) and Darren O'Dea (knee) with the latter out for around six weeks.
Goalkeeper Marton Fulop recovered from a back injury to face Nottingham Forest at the weekend but Keane is likely to put Brian Murphy or Arran Lee-Barrett in against the npower League Two side.
Teenage striker Connor Wickham, Tamas Priskin, Troy Brown, Tom Eastman and Ronan Murray could all also some back into the side as Town make changes for the cup tie.
