Jamie Vardy and Paul Konchesky both returned to training on Thursday and could be in line to face the Tractor Boys.
Striker Vardy had been struggling to shake off a knock while left-back Konchesky had been nursing a hamstring problem.
David Nugent is expected to be fit despite being withdrawn against Nottingham Forest last weekend after suffering a neck injury.
Defender Sean St Ledger remains sidelined with a hamstring problem while loanee Michael Keane has returned to parent club Manchester United for treatment on a hamstring injury also.
Fit-again midfielder Richie Wellens, who has just returned from a loan spell at Portman Road, may well face his former club where he was sent to gain some valuable match-fitness after a long-term knee injury.
Ipswich, meanwhile, could hand debuts to Bradley Orr and Kelly Youga.
Orr arrived on loan from Blackburn this week along with fellow defender Youga, who has penned on a short-term deal until January.
Wide man Lee Martin is also back in contention having served his one-match suspension in last weekend's 2-1 win over Burnley.
Back-up goalkeeper Scott Loach will be assessed having sustained a dead leg during a Suffolk Premier Cup match in midweek.
Striker Paul Taylor (foot) is likely to miss the rest of the campaign.
