Nathan Baker is close to recovering from his hamstring injury - but the FA Cup clash against Millwall is likely to come too soon for the defender.
Baker had to come off in the early stages of last weekend's draw at West Bromwich Albion.
Manager Paul Lambert revealed the England U21 centre-back is almost back to full fitness, although he is unlikely to take part in tonight's fourth round tie at The Den.
Meanwhile, Marc Albrighton and Chris Herd are set for lengthy stints on the sidelines with foot injuries.
Winger Albrighton is facing a spell of eight to twelve weeks out of action, with utility man Herd ruled out for six weeks.
"Nathan's doing ok," said boss Lambert.
"He hurt his hamstring in the West Brom game, but this game is probably too early for him.
"Marc will be about eight or twelve weeks and Chris will probably be about six."
Richard Dunne is also progressing well after recovering from a groin injury but Lambert is likely to resist rushing him back so soon.
"I think Richard's a different case because he's had a major operation," he added.
"That's the big thing with him. Sometimes you'll do that with players, you'll throw them in because you need to and then I'll take the responsibility if they're tired after an hour.
"But with Richard it's a bit different."
