Lions boss Kenny Jackett welcomes back experienced duo Dave Brammer and Richard Shaw to his squad for Saturday's crunch home clash against Oldham Athletic.
Brammer has not kicked a first team ball since sustaining cartilage damage in the 2-1 win over AFC Bournemouth on 20th October.
Defender Shaw has also been sidelined for five matches after hobbling off in the 2-2 draw with Swansea City on 6th November.
However, both men may have to contend with a place on the bench with The Lions winning four of their last five matches.
Fellow centre half Brent Sancho, who has signed on a month's contract, is another addition to Jackett's squad.
Although The Lions were frustrated at the postponement of last Saturday's League One match at Luton Town, the extra few days has provided time for midfielder Ahmet Brkovic and striker Bayo Akinfenwa to recover from injury.
Midfielder Ahmet would have missed the Kenilworth Road clash having picked up a knock in Millwall's 1-0 win at Leyton Orient, while Bayo, who missed the Brisbane Road game with a slight thigh strain, has also fully recovered.
Meanwhile Oldham boss John Sheridan will again be unable to call on the services of skipper Sean Gregan, who is sidelined with an achilles problem, whilst keeper Lee Pogliacomi (knee) and striker Andy Liddell (achilles) are also out.
