Full-back Jack Walker has signed a five-year contract at Leeds Rhinos which will expire at the end of the 2023 season.
The 19-year-old has made 47 appearances, scoring 13 tries since breaking into the Rhinos squad in 2017.
Leeds-born Walker was part of the 2017 Grand Final winning squad at 18 and toured Papua New Guinea last autumn with England Knights.
“It is a great club and I am looking forward to the future,” Walker said.
“We have achieved some great things in the past and hopefully we can emulate that as a group.”
Director of rugby Kevin Sinfield added: “Jack is one of the most exciting talents in our game.
“The club have shown a great deal of faith in Jack throughout his time here and I am confident he can continue to develop and progress in the years ahead.”
