Rhys Priestland has confirmed that he will join Bath when his Scarlets contract expires at the end of the season.
The Welshman will end his 10-year association with the Llanelli outfit to move to the Aviva Premiership after the World Cup and compete with England's George Ford for the fly-half spot at the Recreation Ground.
"My entire rugby career has been spent in Wales and, although I've enjoyed that time enormously, I need a new challenge," Priestland said in a statement.
The 27-year-old, capped 32 times by his country, has scored 1,059 points in 147 appearances for Scarlets.
His switch to Bath may jeopardise his international career when a new selection policy means that players outside of Wales could be excluded from Warren Gatland's plans unless they are signed to national dual contracts.
