Sky Sports sources understand that Nottingham Forest have made a bid for Millwall striker Darius Henderson.
Henderson has enjoyed a fine season to help Millwall mount a challenge for promotion from the Championship.
His fine performances have not gone unnoticed, though, and Forest have been keeping tabs on him as a potential transfer target since Alex McLeish took charge.
It is now understood that Forest have tabled an offer for Henderson, as they seek to strengthen their squad before the end of the month and push on until the end of the season.
Henderson has a lot of experience in the Football League, having started his career at Reading and also spent time with Gillingham, Watford and Sheffield United.
