Freedman is scouring the loan market to bolster his injury-hit squad after seeing Michael Mancienne ruled out for several weeks with a hamstring injury.
Mancienne joins a long list of players on the sidelines for Forest with the likes of Andy Reid, Chris Cohen, Britt Assombalonga, Matty Fryatt, Kelvin Wilson, Robert Tesche, Ben Osborn and Dexter Blackstock all injured, while Matt Mills and Eric Lichaj both face suspensions.
Freedman knows all about Trotter having signed the player during his time in charge of Bolton with the 27-year-old arriving initially on loan from Millwall in January 2014 before the move permanent at the end of that season.
Freedman is keen to bring in a couple of fresh faces before this weekend's clash with Bristol City and Trotter's versatility would make him a valuable addition to the Forest squad.
Forest's only concern is Trotter's match fitness as he has made just one brief appearance off the bench against Derby County this season and Freedman is keen to have a player who can come straight into his side.
