Republic of Ireland under-21 international Michael Keane has joined Grimsby Town on loan until the end of the season.
The Preston midfielder (19) impressed Mariners boss Paul Groves after making 26 appearances for the Lancashire club since his debut last season.
Preston boss Craig Brown told the club's official website: "As Michael has been frustrated that he hasn't been getting any games, this is a good chance to all but guarantee him first-team football".
