The 35-year-old hooker said he could retire after the Storm were beaten by the Sydney Roosters in last year's NRL Grand Final.
Stalwarts Billy Slater and Ryan Hoffman both called time on their careers at the end of last season after Cooper Cronk had departed for the Roosters following the 2017 campaign.
Storm legend Smith will not be following the trio out of the door, though, after agreeing a new deal which is set to see him become the first NRL player to reach the 400-game milestone.
Always. Proud. Forever. Storm.
