Gibbs, who has been with the club for the last eight years, will be contracted with the Tigers until the end of 2014.
The 26-year-old prop has made a total of 135 appearances for the club and was a member of the squad that picked up an NRL premiership in 2005.
“I wanted to stay with Wests Tigers and this new contract means I can be a Tiger for life,’’Gibbs said.
“It’s a great Club to be a part of and I just hope I can contribute to the team’s success in the future.”
Wests Tigers Chief Executive Officer Stephen Humphreys said that the new contract for Gibbs was well deserved.
“Bryce has played his part in helping this developing team become more and more successful,’’ Humphreys said.
“It’s extremely satisfying for the Club to see a product of our development system become an integral member of our NRL squad. I’m sure he has some exciting years to come.”
