Millwall with be without on-loan forward Mason Bennett for the Sky Bet Championship match against Derby.
Bennett is not eligible to face his parent club having joined the Lions at the end of the January transfer window.
Tom Bradshaw and Jon Dadi Bodvarsson are both options for manager Gary Rowett, whose side are closing on the play-offs following an impressive 3-0 win at Nottingham Forest.
Midfielder Ryan Leonard has been sidelined by illness, while Ben Thompson is stepping up his rehabilitation from an ankle problem and goalkeeper Frank Fielding (arm) also continues his recovery.
Derby manager Phillip Cocu expects Wayne Rooney and Tom Lawrence to be available for the trip to south London.
Veteran Rooney missed the 3-0 home victory over Blackburn with a minor muscle problem but has returned to training.
Forward Lawrence picked up a calf injury in the FA Cup fifth-round defeat by Manchester United and is also likely to be involved again.
Midfielder Tom Huddlestone has resumed training as he steps up his rehabilitation following more than a month out with a calf problem.
