Fulham will be Harrison Reed, Anthony Knockaert, Terence Kongolo and Harry Wilson as well as Tom Cairney at Millwall on Tuesday night.
Wilson is suspended after being set off in the 5-1 win at Huddersfield on Saturday, and the others are still struggling for fitness.
Boss Marco Silva reckons his side need to show “character” against the Lions, but adds plenty of his squad have faced Millwall in the recent past.
Silva said: “A big part of our squad has played them both home and away, so we know what we face. And this kind of game will show our character.”
The manager is also hoping André-Frank Zambo Anguissa will stay despite reported interest from other clubs.
He said: “We’d like to keep him, of course. He’s a different (player) to what we already have, and I am working with him to get the best performance from him. But during the market everything can happen.”
