Derby County have increased their defensive options after signing teenager James Tomkins on loan from West Ham United.
Paul Jewell has been short of cover at the back and has secured a deal for Tomkins until the end of December.
The 19-year-old has not featured for West Ham this season due to a knee injury, but has made six appearances since making his debut in March.
He is highly rated at Upton Park and the England youth international is looking forward to his stint with Championship side Derby.
"I have got to challenge for my place at West Ham United, but if I can get a few games under my belt in a good league, then it can only be good for me," Tomkins told the club's official website.
"Derby have a good stadium and fans. Obviously it will be good experience, I am looking forward to it - having some games, I know I have to impress before I play [at West Ham], I won't just walk into the side.
"My total aim is to play for West Ham, but if I have to go out on loan somewhere else to get some more experience, especially in what is a very tough league, then it can only be good for me for the future.
"I can then come back to West Ham and stake my claim for a place here. Going on loan is an important part of a young player's development. I am only 19 and still learning the trade so this can only do me good."
