Dane Chisholm has put pen to paper on a three-year deal with Featherstone.
The 28-year-old half-back joined the Rovers back in April on a season-long loan from Championship rivals Bradford.
A former France international, Chisholm will remain at the LD Nutrition Stadium until at least the end of the 2022 season.
Chisholm said: “I have really enjoyed my time here so far, I have been playing some pretty good rugby and am getting a lot of support on and off the field.
“The recruitment work being done by the club for the years ahead is very exciting and I am buzzing to be a part of it. This is a great club to be representing and everything is heading in the right direction.
“I don’t want to think too far ahead because we want to do something very special this season.
“However, the building work is progressing here and the plans for the future are encouraging. We are building towards achieving more and more success.
“The team spirit is fantastic and we are all looking forward to the massive games coming up, as we look to nail down a place in the play-offs over the coming weeks.”
