Jay Tabb is a doubt for Ipswich's home clash against Millwall.
The left-sided midfielder is struggling with a shoulder injury having been withdrawn just 35 minutes into Tuesday's shock 2-0 Capital One Cup defeat at Stevenage, where boss Mick McCarthy made six changes to his starting XI.
As well as Tabb, left-back Aaron Cresswell (thigh) will also be assessed having returned to training this week.
But Anthony Wordsworth (calf) and Tyrone Mings (knee) continue to miss out.
Millwall boss Steve Lomas could include new signing Shaun Derry.
The veteran QPR midfielder joined the Lions on a month's loan deal on Thursday and is likely to play some part at Portman Road on Saturday.
Goalkeeper David Forde will be out until next month with the knee injury he sustained in last weekend's 1-0 defeat to Yeovil, so Stephen Bywater will start once again.
Veteran stopper Andy Marshall has been brought in on a short-term deal as cover for Bywater, and he is expected to feature on the bench.
