Wales international Tavis Knoyle is to link up with his former boss Nigel Davies at Gloucester.
Gloucester have announced a two-year deal for scrum-half Knoyle, who will move to Kingsholm from the Scarlets. Knoyle, 22, has won nine caps and was part of Wales' 2011 World Cup squad in New Zealand.
"I obviously worked with Tavis from his arrival with the Scarlets," said Gloucester rugby director and ex-Scarlets chief Davies.
"He is a very talented scrum-half and a real competitor.
"He will add something else to our squad. We've already got two fine scrum-halves in Jimmy Cowan and Dan Robson, and Tavis will complement them nicely.
"At 22, he is also still a very young player, despite his considerable experience. His best years lie in front of him and, hopefully they will be with Gloucester."
Knoyle, who has been selected for Wales' two-Test Japan tour next month, will follow his fellow international George North from the Scarlets and into the Aviva Premiership next term following North's switch to Northampton.
"I am extremely honoured and excited to sign for Gloucester, for a whole host of reasons, but not least the passionate supporters, the quality of the playing squad, the famous history of the club and because of Nigel Davies, who was my coach at the Scarlets," Knoyle said.
"I would like to thank the Scarlets and their supporters for the support I received while at the club, but I now look forward to my immediate future at Kingsholm."
