The talented youngster will return to Manchester United, following an operation on a knee injury that he picked up in training ahead of the game with Cardiff.
“I’m not looking at the moment to replace him. He’s having the op, so he’s got to go back,” Ferguson told North End’s official website.
“I’m happy with the three we’ve got. Neil (Mellor) is scoring goals at the moment; I thought Browny (Chris Brown) gave a good performance against Sheffield Wednesday and Parky (Jon Parkin) has been in good form recently.”
