PA:
The Rams have confirmed that a fee, reported to be £1million, has been agreed for the 22-year-old.
Now manager Billy Davies plans to discuss personal terms with the player who has so far made four first-team appearances for United, two of which have come in Carling Cup ties this season.
Jones scored three goals in 25 appearances while on loan at Preston last season - where he played under Davies - before spending five months with Dutch side NEC Nijmegen where he played on the left side of a three-man midfield.
Jones also has one England Under-21 cap to his credit and could be signed in time to feature against Luton at Kenilworth Road on Saturday.
Billy Davies:
"David is a player I have admired for a long time and he did a wonderful job for me at Preston.
"He is a talented young player. He has great ability and vision and can create and score goals."
