Several players have had limited game time during the close season and it is clear that Preston are willing to entertain offers for players such as Boyle, Doyle and O'Connor.
The latest transfer speculation has linked non-league Salford with a move for youngster Conor Simpson who has barely featured since his move from Hartlepool back in January.
Simpson is one for the future and is unlikely to feature much this season. In addition there was also a suggestion that Horgan was interesting the non-League club although given his impressive form in pre-season this would be an unlikely move.
