The 23 year old is looking for a move after saying that he no longer wants to play for Rovers, even though he signed a five year contract in 2010.
Speaking to BBC Radio Lancs, Kean said: "He's asked for a transfer, hence why he never went to Austria. He doesn't want to play for the club any longer."
He added: "I had two meetings with his father and he wants to play elsewhere. We'll be listening to offers, but as it stands he remains under contract and we haven't had any offers at all."
