Joe Mattock and George Thorne have been added to the Portsmouth squad.
Full-back Mattock and midfielder Thorne have joined Pompey on loan after new boss Michael Appleton raided his former club West Brom.
Mattock could be in from the start against the club where he began his career while Thorne may start on the bench.
On-loan Manchester City midfielder Abdul Razak's display as a substitute was one of the few bright spots of last week's defeat at Watford so he may have earned himself a start, especially if skipper Liam Lawrence is ruled out again with his ankle injury.
Defender Hermann Hreidarsson is still building up his fitness after a spell out with an Achilles problem.
But Sol Bamba comes back into the reckoning for Leicester ahead of the trip to the south coast.
Bamba served a one-match suspension as the Foxes got off to a winning start against Crystal Palace in Nigel Pearson's first game back as manager last Sunday.
Sean St Ledger stepped in for the big defender and Pearson must decide whether the Republic of Ireland international keeps the shirt or if Bamba is restored to the starting XI alongside captain Matt Mills at the heart of the backline.
Lee Peltier was substituted as a precautionary measure during the second half of the 3-0 victory over Palace after complaining of a tight hamstring.
However, the full-back has trained all week and will be fit.
