Derby County have signed David Nugent from Middlesbrough for an undisclosed fee, the Championship side have announced.
Former England international Nugent has signed a two-and-a-half-year deal with Steve McClaren's promotion-chasing Rams.
The 31-year-old former Leicester and Portsmouth forward helped Boro to promotion from the second tier last season but has made just five appearances for Aitor Karanka's side this term, the last coming in September.
Rams boss McClaren, who handed Nugent his only England cap, told the club's official website: "He is a proven goal scorer at Championship level and he also has a great deal of experience as well to bring to the table.
