Leicester Tigers have signed Dom Barrow from Newcastle Falcons after the second-row forward activated a release clause in his contract.
The 22-year-old was in the England U20 side that won the 2013 World Junior Championship and played 37 games for Falcons after joining in 2013.
Director of rugby Dean Richards told Newcastle's website he was "bitterly disappointed" Barrow had left.
The length of Barrow's deal has not been disclosed.
Tigers director of rugby Richard Cockerill was thrilled to sign Barrow, who is recovering from a cruciate knee injury.
"He is a big, athletic second row who has already gained Premiership Rugby experience," Cockerill said.
"We think he can only improve working with a very good group of second rows here including Graham Kitchener, Ed Slater, Sebastian De Chaves and our new signings Mike Fitzgerald and Mike Williams."
