Leicester boss Sven-Goran Eriksson has no new problems.
The Swede made four changes as the Foxes returned to winning ways and moved to within a point of a Championship play-off spot with a 2-0 victory over Watford at the King Power Stadium on Wednesday.
Sean St Ledger replaced suspended captain Matt Mills at the centre of defence and Eriksson is unlikely to alter his back four after a clean sheet, with Mills set to serve the second game of his three-match ban.
Jermaine Beckford was another to be recalled against the Hornets and he could also keep his place after scoring his first goal for the club.
Changes are likely elsewhere for Leicester's third game in the space of seven days.
Midfielders Gelson Fernandes and Neil Danns, winger Lloyd Dyer and strikers Steve Howard and Darius Vassell are options for Eriksson, while teenage sensation Jeffrey Schlupp could also return to the squad.
Therry Racon could return to the Millwall squad for the trip.
The midfielder, a summer signing from Charlton, has been sidelined since suffering an ankle injury on his debut in August but now has two reserve games under his belt.
Racon could be added to the bench as manager Kenny Jackett may stick with the side which battled to a 1-1 draw against Brighton on Tuesday night.
Shaun Batt also played for the second string this week, his first action in 15 months after a cruciate injury, but he came off as a precaution with a groin niggle.
Fellow striker John Marquis is still sidelined following a hernia operation so Jay Simpson continues in attack after his goal against Brighton.
