North End are a senior keeper short after Lindegaard departed the club after his one year contract expired. It was expected that Grayson would move for a replacement to challenge Maxwell for the number one sport.
Rudd was linked with Preston towards the end of the season as he was out on loan at Charlton with his Norwich contract set to expire. He has since signed a new deal at Norwich and for a time looked like he was going to be their number one for next season.
The Canaries are under new management and it now appears that Rudd has dropped down the pecking order. The young keeper is seeking a move away and Preston may well make a move for the keeper.
