The Seasiders' longest-serving player, Gilks arrived at Bloomfield Road from Norwich City in the summer of 2008.
The keeper endured a frustrating time at Carrow Road trying to displace Andy Marshall in the Canaries goal and joined the Seasiders to compete with Paul Rachubka for the number one jersey.
Displacing Rachubka was initially a hard task - he joined Shrewsbury in search of first-team football on loan in November 2008 - but he enjoyed greater success when Ian Holloway arrived as manager.
Since then the 31-year-old has gone from strength to strength between the sticks and played a big part in the club's promotion to the Premier League, although he missed a number of months in the top-flight due to a broken knee-cap.
Gilks has now been back to his best form for the past two seasons and he made a total of 48 appearances for The Seasiders in the last campaign.
