Scrum-half Nick Runciman has rejoined London Welsh ahead of their maiden Aviva Premiership campaign.
The 26-year-old spent last season with Gloucester, having left Welsh after a three year stint at Old Deer Park.
Runciman, who also previously played for Worcester and was capped by England at age-grade level, made 15 appearances for the Cherry and Whites but will be hoping for more first-team opportunities with the Exiles.
"I'm very pleased to be back - it feels like I've never been away," said Runciman.
"It's a great place to play rugby, a great bunch of lads and I'm looking forward to playing under Lyn [Jones - head coach].
"I watched all of London Welsh's televised games last season and kept my eye on their results. It was great to see the boys win the Championship the way they did. It was testament to the professionalism of the lads and the coaching staff at the club.
"Gloucester definitely benefited my game. I feel fitter than I've ever been and my game management's improved, and hopefully I can add that to the London Welsh squad."
