Bath have signed Wales and British & Irish Lions scrum-half Rhys Webb on a deal until the end of the season.
The 31-year-old left French side Toulon last month and has agreed a contract with Ospreys from next season, but will play in the Premiership for the next four months.
Director of Rugby Stuart Hooper told the Bath website: "We're very excited to bring in an international talent."
Webb could make his debut in the derby against Bristol on Sunday, 1 March.
Hooper said Webb, who has won 32 caps for Wales and played in the Six Nations game against Italy earlier this month, will add depth and quality at a "critical time of year" which has seen Max Green sidelined with a fractured leg.
"A signing of this calibre is something I know will be welcomed by the squad," he added.
"I'm sure he'll settle in quickly and I know he is looking for some game time as soon as possible."
Webb remains eligible to play for Wales in the Six Nations after being given a six-month dispensation by the Welsh Rugby Union in January 2020.
He had previously been ineligible for international selection since the WRU brought in a policy in October 2017 that meant players would not be picked if they had won fewer than 60 caps and opted to move away from Wales.
