Defenders Abu Ogogo and Paul Rodgers and midfielder James Dunne are currently training with Forest with the view to landing deals.
"Nottingham Forest have said they will have a look at them for 10 days and let them play in their reserves, with a view maybe to offering them a contract. We try to help them every way we can.
"At the moment we don't know what the all-round situation is but they have been allowed to go up there to work with [Forest manager] Colin Calderwood.
"We like to look out for all our players at the Club and if it maybe isn't going to happen for them here we try to get them a place at another club as soon as we can to help them on their way in their career."
