Keane, who has the ability to play across the backline and midfield, offers North End options. The former Irish U21 international was a one club man before joining North End in what was a busy summer of 2012 at Deepdale.
Making his debut as a 16-year-old in 2003, Keane made over 260 appearances for the Hatters – plying his trade in four divisions - from the Championship to the Blue Square Bet Premier.
Keane has stayed loyal to Luton in recent years and quickly became a huge fans’ favourite at Kenilworth Road, winning the supporters’ player of the year on back-to-back occasions.
Keane’s efforts couldn’t prevent Luton suffering Play-Off heartache in his last two seasons at the Club, with the Hatters falling to both AFC Wimbledon and York City in their bid to win promotion to the Football League.
A long-time admirer of Keane’s abilities, North End snapped up the 25-year-old with the temptation of returning back to League One too hard to turn down.
And Keane made a lasting impression on the Lilywhites' faithful with his no nonsense, tough tackling style of play, racking up 31 appearances in his debut season.
The midfielder continued to feature regularly for Preston during the 2013/14 campaign under Simon Grayson.
He played in 41 games for the Club, scoring one goal away at Gillingham, and often captained the side in the absence of John Welsh.
