Trotter, Henderson and Henry in contentionStriker Paul Taylor has a long-term foot injury so will miss out but Luke Hyam could come back into the fold after missing last weekend's win at Bolton with a calf injury.
Former Lions manager Mick McCarthy, now in charge of The Blues, looks set to be without experienced midfielder Nigel Reo-Coker who has a hamstring problem.
Trotts has recovered from a hamstring injury in time to face his former club, with Henderson also back after overcoming a similar problem which he picked up in the November draw against Watford. James, who missed last Saturday's stalemate against Charlton Athletic, is back from a calf niggle.
Liam Trotter, Darius Henderson and James Henry have all been in training this week and could return to the squad as The Lions bid to make it 14 games unbeaten against an improving Ipswich side.
Kenny Jackett is hopeful that three key men will be back in contention for Millwall's game at Portman Road on Saturday.
