Roosters lock in Daniel Tupou until 2021

Sydney Roosters have locked up former NSW State of Origin winger Daniel Tupou until the end of the 2021 NRL season.

Tupou, who played four games for the Blues in 2014 and 2015, was off contract at the end of the season but signed a four-year deal on Monday.

"Every chance I get to represent the Roosters is a special one," Tupou said.

"Robbo and the coaches have taught me so much and I'm proud to be part of the team here, so I'm stoked to extend with the club."

Roosters coach Trent Robinson praised Tupou as "a highly-valued contributor to our team”.

“’Toups’ has an outstanding work ethic and holds himself accountable, and away from footy, he’s a great man and mentor to the younger members of our squad, so it’s great to know that he will continue to be part of our team for at least the next four years,” Robinson said.

Tupou's signing adds another piece to the Roosters' backline puzzle for next year.

They have already confirmed James Tedesco's arrival at fullback, while Michael Gordon is expected to move to the wing and play on another year.

Current Blues winger Blake Ferguson is yet to be re-signed, while regular centre Shaun Kenny-Dowall was released earlier this year after a drug charge.

Tupou, 26, has scored 65 tries in 111 NRL matches for the Roosters since his 2012 debut.
