The 24-year-old, who scored nine goals from defence in 2011/12, turned down a new deal at the Lamex Stadium, along with a number of Championship suitors, to agree a two-year deal at Deepdale.
Laird began his journey at Plymouth Argyle and progressed through the club’s youth system, but only made one first team appearance.
Loan spells at Tiverton Town and Torquay United soon followed before he impressed whilst on loan at Stevenage, persuading him to join the club on a permanent basis in February 2008.
The young defender quickly established himself in the starting line-up and won the player of the year award at the end of the 2008/09 season after Boro won promotion to the Football League. His success continued at the Herefordshire side as Stevenage won back-to-back promotions to League One.
A former England C international, Laird continued to show his credentials by becoming one of the best left backs outside the Premier League and helped Stevenage to the League One Play-Off semi-finals.
Sadly for Laird, Stevenage weren't able to secure promotion through the Play-Offs and his contract was due to run out at the end of the season.
North End duly swooped for the defender in the summer of 2012 and were more than satisfied with his efforts in his first season with the Club.
The left back managed a total of 24 appearances for the Lilywhites before he broke his leg just three months into the 2012/13 campaign, causing him to miss the rest of the season.
Laird returned to action the following pre-season in a warm up match against Premier League giants Liverpool and, despite fighting David Buchanan for playing time at left back, he finished the 2013/14 campaign second on the Club's assists list.
Overall, Laird made 42 appearances for North End during the season, scoring a goal against former club Stevenage in September as the Lilywhites stormed to a 3-0 win.
