Leicester Tigers have signed centre Jack Roberts from Championship side Rotherham Titans.
The 22-year-old ex-Wales Under-16 and U-18 international spent one season with the Titans, scoring 12 tries in 36 games to help them reach the play-offs.
Rotherham head coach Lee Blackett said: "It's obviously massively disappointing to lose a player as good as Jack.
"He's done a fantastic job for us and he is destined to reach the top. There can be little doubt about that."
Tigers director of rugby Richard Cockerill said: "Jack is a young and ambitious player who we have seen play well in Championship company.
"Now he has an opportunity to take that potential into a Premiership club."
