The Reds have already confirmed one deal with Manchester City loanee Greg Cunningham set to stay at the club until the end of the season after making the problem left-back slot his own over the past couple of months.
"He's a really good footballer and a fantastic lad - he has fitted in around the place very well," Steve Cotterill told the official club website.
A signing that is being reported but has yet to become official meanwhile is that of Marlon Harewood on a deal until the summer.
The former Forest favourite has been training with the Reds recently following his return from a spell playing in China.
Potentially going through the City Ground exit door are Chris Gunter, Wes Morgan and Ishmael Miller.
Norwich City have joined Fulham and Blackburn Rovers in being linked with Gunter, Reading and Cardiff are being credited with an interest in Morgan and Middlesbrough are seen as likely suitors for Miller.
