Derby midfielder Stephen Pearson's return from injury has been put on hold by Rams manager Billy Davies. He was expected to feature in Tuesday's friendly against Notts County at Moor Farm, but will now play no part.
The 24-year-old Scotland international was injured in the defeat at Sunderland a month ago and has missed the Rams' last five matches.
Davies said: "Tuesday's game is too early for him. He is touch and go for Saturday, we'll have to wait and see."
