Rumoured to be heading to the City Ground ahead of Thursday's 5pm loan deadline is Scotland international midfielder Graham Dorrans.
Out of favour at the Hawthorns, 26-year-old Dorrans has not featured for West Bromwich Albion in the Premier League since August.
Guy Moussi, meanwhile, impressed on his debut for Millwall on Saturday after his loan switch from Forest. Lions boss Steve Lomas saying of the midfield man's performance against Barnsley: "I thought he did okay for a guy who hasn't played much football and who only came back from a groin injury about three weeks ago.
"Guy did really well to get through the 90 minutes and, with Nicky Bailey suspended for the Leicester game, he'll certainly play an important part next weekend."
Ex-Reds' goalkeeper Lee Camp is currently back in the Championship and has extended his loan stay at Bournemouth from West Brom until the start of January.
