Penrith prop Moses Leota has signed a three-year extension with the Panthers, which will see him remain at the club until at least the end of the 2022 season.
The 23-year-old was already contracted for next season, meaning he'll be spending the next four years at the foot of the mountains.
"It feels great to have re-signed and to know I'll be at Panthers for the next four years," Leota told penrithpanthers.com.au.
"With the players and staff we have, I think we're in a strong position to push for a premiership. That's a big motivation for me.
"This is the club that showed faith in me from the very beginning and now it's my time to give something back.
"I want to thank the Panthers members for their support. I can't wait to see them again in 2019."
Leota played 20 first grade games for the Panthers in 2018, and averaged 20 tackles and 60 running metres per game.
"Moses is one of the hardest working young men I have encountered in all my time in rugby league," Panthers' Executive General Manager Phil Gould told the club's website.
"He is another success story emerging from the club's junior development pathways and he deserves everything he gets out of the game due to his unconditional commitment.
"We're delighted Moses will be part of our club for the next four seasons."
