Chris Kirkland and Roman Bednar are likely to make their Foxes debuts in the East Midlands derby at home to Forest.
Both players were signed by Sven-Goran Eriksson in deadline-day deals - keeper Kirkland on a one-month loan from Wigan while West Brom striker Bednar will stay at City until January.
Eriksson will pick two from a strong group of strikers that now includes Bednar, Martyn Waghorn, Darius Vassell, Steve Howard and Matty Fryatt to start the game.
Leicester are confident that leading scorer Andy King will be fit.
The seven-goal midfielder had been a doubt earlier in the week after limping out of the defeat at Bristol City with a hamstring problem.
Loan signings Aaron Ramsey and Marcus Tudgay are in line to make their Forest debuts on Monday night.
Boss Billy Davies pulled off a sensational deadline-day deal in bringing Ramsey to the City Ground and the Arsenal midfielder is poised to make his long-awaited comeback from a broken leg.
With Dexter Blackstock now a long-term absentee after suffering cruciate knee ligament damage at Cardiff last weekend and David McGoldrick also out with a knee problem, Tudgay is also a strong contender to start after arriving from Sheffield Wednesday.
Nathan Tyson is available again after missing the trip to south Wales through illness but fellow forward Robert Earnshaw is a doubt after missing a couple of days' training this week due to a virus.
Defender Kelvin Wilson may be in contention. He has missed the last four games due to a back problem but successfully came through a 45-minute reserves run-out on Wednesday.
Captain Paul McKenna (groin), fellow midfielder Paul Anderson (hamstring) and defender Brendan Moloney (hamstring) are doubts.
