Sky Sports understands that Derby are close to completing a deal for Kieron Freeman, with the youngster set to join from arch-rivals Nottingham Forest.
Sky Sports revealed on Monday that the Rams had leapt to the front of the queue for the promising defender.
Freeman has expressed a desire to move on this summer after finding his route to first-team football blocked at the City Ground.
Forest will not stand in his way and are prepared to part with the Wales U21 international.
Notts County had been hoping to reach an agreement after seeing Freeman impress during a loan spell at Meadow Lane last season.
Derby are, however, set to secure his signature, with Nigel Clough making no secret of his desire to bring in defensive reinforcements.
It is understood that Freeman will undergo a medical on Friday before crossing the East Midlands divide and completing a switch to Pride Park.
