Brown, 25, has moved to Craven Park on a one-year deal from Batley after an impressive 2012, which saw him score 10 tries and earn a place in the Championship Dream Team.
Previously with Huddersfield, he made just one top flight appearance with the Giants, before initially being loaned out to the Bulldogs, and then joining them permanently after a brief stint in rugby union with Sale Sharks.
He told the Rovers’ official club website: “The move first came about after James Green, who was on loan at Batley, was being watched by Craig Sandercock. I obviously impressed him because he offered me a chance and I took it with both hands.
“The chance to play at this level again is rare after dropping down a grade so I am one of the lucky ones I suppose. This is where I am now and this is where I want to stay, so I will be working hard towards claiming a starting spot but I know that’ll be tough with so many quality backs here.
“I am buzzing to be back in a fulltime environment though. At Batley I was getting up at 5:30am to go and collect scaffolding poles for the day’s work and then having to go training after that. So getting up knowing that I am coming straight here is brilliant. It makes me work a lot harder because it is always in the back of my mind that I could be throwing poles around instead of playing rugby league for a living.
“I can’t wait for the friendlies to come around, I feel ready to play tomorrow. I want to try and impress the coach as much as I can to stake my claim for a starting spot come round one.”
A Jamaica international, Brown played in their 36-26 defeat against USA in the 2010 Atlantic Cup in Jacksonville.
He started his career at Keighley, moving on to Rochdale before being signed by Huddersfield ahead of the 2009 season.
