Stuart Gray is still waiting on the 'green light' to bring in new players as his hands are tied by a takeover delay.
Millwall have signed midfielder Guy Moussi on loan from Nottingham Forest.
The 28-year-old Frenchman has agreed a switch to The Den until January 2 having found first-team opportunities limited with Forest this season.
Manager Steve Lomas moved for Moussi after Shaun Derry left to become manager at Notts County.
Lions assistant boss Mick Harford told the club website: "Shaun left us last week and we wanted some competition in midfield.
"Guy is big, strong and athletic, and that's exactly the type of player we've been looking for."
