Worcester have signed Wales and Cardiff Blues scrum-half Ryan Powell on a two-year deal.
Powell has spent seven seasons with Cardiff
The 25-year-old has three caps, and will complete his move to Sixways at the end of the season.
"Ryan has all the qualities to be successful in the Premiership," said Worcester director of rugby John Brain.
"He will add to the depth of resources we have at scrum-half and greatly increase the amount of competition for a starting spot."
Powell will compete with former England scrum-half Andy Gomarsall for a place in the Warriors line-up.
"These are exciting times for me as a player," said Powell.
"It's a great opportunity and I am looking forward to the challenge of playing in the Guinness Premiership and coming up against some of the best scrum halves around every week.
"My main priority is to win the confidence of the players and coaches and to secure a starting spot."
