Penrith Panthers is delighted to announce Josh Mansour has signed a new three-year deal with the club.

The contract extension means the 27-year-old winger will remain with Panthers until at least the end of the 2021 season.

"I'm extremely grateful and excited to have committed my future to Panthers," Mansour said.

"This club has given me everything and shaped me into the person I am today, on and off the field.

"While I had to consider my options, my overwhelming desire was to stay at Panthers as my heart has always been with this club.

"I feel I've still got unfinished business here and I can't wait to serve the club for another three years."

After playing his junior football with South Sydney, Mansour joined Panthers in 2012 and made his NRL debut in Round 9 of that year.

He has gone on to score 55 tries in 108 appearances for Panthers and in 2016 was named Dally M Winger of the Year.

His representative career includes appearances for Lebanon (2009), NSW City (2016), NSW Blues (2016) and Australia (2014-17).

"I want Josh Mansour to be a part of Panthers for the rest of his life. I can give him no greater accolade," Panthers Executive General Manager Phil Gould AM said.

"His contributions both on and off the field have been nothing short of outstanding."

Mansour is currently sidelined as he recovers from facial fractures but is hopeful of returning for the Panthers later in the season.
