Blair, 25, has signed a four year deal with the club from next season and will add an edge to the Tigers forward pack.
Wests Tigers CEO Stephen Humphreys said the Club was delighted to have secured the services of Blair.
“Adam is a world class forward who has been a key member of the very successful Storm side in recent years,” Humphreys said.
“His experience, leadership and professionalism will be great assets to our Club.”
“The recruitment of one of the game’s best forwards in Adam Blair, along with the depth and experience provided by both Joel and Matthew, will blend very well with the existing and emerging talent we have in the Wests Tigers roster,” Humphreys said.
