Two-time premiership player Luke Lewis has announced his retirement from the NRL, revealing tonight that he will finish his decorated career at the end of 2018.

The 34-year-old made his NRL debut with Penrith in 2001 and played on the wing in the Panthers' 2003 premiership-winning side.

After 12 seasons and 208 games with Penrith, Lewis joined the Cronulla Sharks in 2014 and tasted grand final glory again his third season in the Shire.

Lewis played back row in Cronulla's memorable 14-12 win over the Storm in the 2016 decider and capped a magnificent game by taking home the Clive Churchill Medal as the best player on the ground.

Lewis played 16 Test matches for Australia and 17 Origins for NSW. He was part of the Blues' series wining sides in 2004 and 2014.

A member of the elite 300-game club, Lewis is one of the most respected figures in the NRL and his Sharks team-mates will be doing their utmost to send him out with a third premiership.

"It's been an awesome 18 years and I've loved every minute of it. I'll retire with great memories," Lewis told Sharks Media.

"My family and friends have obviously given me great support over the years, I've made long-time and what will be life-long friendships, with people in and around the game but also outside of footy. And I also want to give a massive thanks to the fans.

"I've had fantastic support, not just at the Sharks, not only when I was at the Panthers, but from rugby league fans in general, people who have always supported and stuck by me. I couldn't have got to where I am now without them.

"Growing up in the area and playing for Penrith was a huge thrill for me and I'm thankful for the years I spent at the Panthers and I'm grateful for the opportunity to come to the Sharks six years ago.

"Playing in a grand final at the Sharks and to win the first premiership in the club's history, the mates I've made while I've been here, it's something I'll hold close for the rest of my life."
