Martin Rowlands is added to the Millwall squad for the visit of Forest.
The midfielder has moved to The Den on a month's loan from London rivals QPR.
Lions boss Kenny Jackett swooped for the experienced Irishman after learning Jimmy Abdou is facing a spell on the sidelines with a knee ligament injury which could keep him out until mid-April.
Rowlands, Arsenal loanee Craig Eastmond or Tamika Mkandawire will replace Abdou in the centre.
Striker Josh McQuoid could return to the squad following an ankle injury which has kept him out since January.
But Lions stalwart Neil Harris may start alongside top scorer Steve Morison in attack after grabbing his second goal in two games as a substitute against Reading in midweek.
Paul Konchesky has added to Nottingham Forest's growing injury problems ahead of the trip to face the Lions.
The on-loan Liverpool full-back was forced off with a hamstring injury midway through the second half of the home draw against Preston.
Forwards Nathan Tyson and Robert Earnshaw missed out in midweek with ankle and back problems respectively, and all three players are considered doubts.
Boss Billy Davies is boosted by the return of Radoslaw Majewski after the Polish midfielder completed a three-match suspension against Preston.
However, the Scot will continue to be without defender Kelvin Wilson, midfielder Guy Moussi (thigh) and strikers Robbie Findley (thigh) and Dexter Blackstock (knee).
Joel Lynch is likely to come into the side if Konchesky misses out, while Dele Adebola and Garath McCleary are also available for recalls.
