Chesterfield have signed West Brom defender Jack Fitzwater.
Fitzwater has joined on a 28-day loan.
Fitzwater, 17, has been training with the League One side and could play against Colchester on Saturday.
Manager Dean Saunders gave further details on his latest addition: "He's played for the West Brom first team and he comes recommended to me by Tony Pulis.
"We are a bit short of defenders at the minute and he's a young player who might be able to come in and help us. He hasn't looked out of his depth in training so we'll make sure he's ready to play in League One."
