Catalans forwards Louis Anderson and Lambert Belmas have signed new deals with the club.
Anderson, 32, became the third overseas player to notch a century of appearances for the Dragons earlier this year, and has signed a one-year extension.
Meanwhile prop Belmas, 20, has penned a two-year deal.
Former New Zealand international Anderson said: “I’m very happy to stay at the Dragons for one more year. I know something exciting is about to happen. This place is special to me and I’ll ready to work hard for next season.”
He has scored 33 tries in 119 appearances since moving from Warrington.
At the other end of his career is Carcassonne born Belmas, who joined the club’s academy in 2015.
Belmas made his Super League debut against Huddersfield in April and is in the France squad for the upcoming World Cup.
He said: “I’m happy to stay at the club and really proud to see the faith the club and the staff have in me.
“I know I still have a lot to learn but it’s a chance and a privilege to train alongside experienced players who love to share with us.
“I am at the moment focused on the World Cup, I really want to give my best for my country but I really look forward to coming back to Perpignan to start the preseason with the Dragons.”
Still without any new faces for 2018, coach Steve McNamara was pleased with these resignings.
He added: “I am delighted with the resigning of both Louis and Lambert.”
“Louis has been tremendous for the club and even at the later stage of his career is in outstanding physical shape and has a willingness to continue improving his game. His experience and leadership will be vital for us moving forward into 2018.”
“Lambert is a young man with huge potential, his development is something I am really looking forward to playing a part in. I am sure he will put a huge amount of pressure on our established props in 2018 and I look forward to his return from the World Cup to commence what will be an important pre-season for himself. “
