The Chairboys midfielder has missed the last two matches with a hamstring injury which looks certain to keep him out of action once more.
Manager Gareth Ainsworth remains short of midfield cover in Lewis' absence and also in defence. Brentford loanee Aaron Pierre is set to be in the squad with fellow defenders Charles Dunne (leg), Gary Doherty (arm) and Tommy Fletcher (thigh) all sidelined.
Meanwhile, striker Reece Styche is likely to be included after missing last weekend's clash with Southend as he was on international duty with Gibraltar.
