Bradford Bulls have signed Harlequins scrum-half Luke Gale on a two-year contract from the end of this season.
The 23-year-old is the London side's leading scorer and has been one of their stand-out performers this season.
Bulls coach Mick Potter said: "Luke is a player we have had our eye on for some time and I am delighted he has chosen to join us.
"He can run the team around the park, has a great kicking game and will be a great addition to our squad."
Gale started his career in the Leeds academy before moving to Doncaster, where he won National League Two Young Player of the Year for 2008.
He joined Harlequins in 2009 and has made 68 appearances for the London club, scoring 20 tries, 83 goals and four drop goals.
"Bradford Bulls are a massive club and I'm really looking forward to joining them," the Leeds-born player said.
"I had three years at Harlequins and thought it was the right time to move.
"I'm looking forward to the chance of playing in front of so many fans. That's what rugby is all about and if you can't play in front of 10,000 people then you shouldn't be in the game.
"Hopefully I can help them fight for that top-eight slot.
"I don't know Mick Potter that well but the players I have spoken to from his club have said a lot of good things and I'm sure he will help me to improve my game."
Quins head coach Rob Powell told his club's website: "Luke has decided his future lies up north and as a club we respect this. We wish Luke well and thank him for his time over the last three years."
