The paper claims Cardiff made a bid to take Cort for the whole of the coming season but the offer was rejected by Newcastle United.
The £7m rated striker has had injury problems at Newcastle and has only scored 8 goals in three seasons. He has joined the Magpies for pre season training.
He has been the subject of potential loan moves and a player swap with Spurs' Stephen Carr but all these moves failed.
Bobby Robson is reluctant to let him go he wants to be covered in attack in case of injuries.
