Gene began his English career at Craven Park in 1996

The 32-year-old Papua New Guinea international has cut short his spell at Bradford to try and help his former club stay in the top flight.

"It is the club that gave me my chance and it has always been my dream to play for Rovers in Super League," he said.

"I asked to be released so I could come back to Rovers while I was still playing at the top of my game."

Gene began his career with Hull KR in 1996, scoring 94 tries in 111 appearances.

He moved to neighbours Hull and Huddersfield before joining Bradford last year on a two-year deal.

The Bulls agreed to release him from the final 12 months of his contract following the signing of Wakefield's David Solomona.

"Stanley has been a great player during his time at Bradford and performed so well for the Bulls," said Bradford coach Steve McNamara.

"This deal certainly suits both clubs. It's a fantastic opportunity for Stanley to prolong his career at the club he owes so much too."

Gene is the fourth Hull KR signing of the off-season, following the captures of Michael Vella (Parramatta), Jim Gannon (Huddersfield) and Mark O'Neill (Leeds).

"The signing of Stanley is a significant one - and as a newly-promoted club, for us to be able to sign a player of Stan's calibre is fantastic," said chairman Neil Hudgell.

"Stan is one of the game's greatest characters and will definitely be a fans' favourite here.

"His knowledge of the game enables him to be looked upon as a great mentor for some of the younger players."
