Warrington Wolves have signed Hull FC winger Tom Lineham on a four-year deal to start in the 2016 season.
They have paid £140,000 for the 22-year-old, who is Super League's second-highest try-scorer this season with 15.
He has scored 44 tries in 59 Hull FC appearances since his debut in 2013.
Warrington head coach Tony Smith described Lineham as an "outstanding talent", adding: "Tom's try-scoring speaks for itself and he is a player I have greatly admired for years."
Hull FC, meanwhile, have taken up an option to keep utility back Curtis Naughton for a further year and offered him a new deal.
"He has had to wait patiently for his opportunity but continued to push really hard for a chance and when it came he took it with both hands," said head coach Lee Radford.
