Wales international Liam Williams will head to Pro 14 club Scarlets with immediate effect from English club Saracens.
Williams already featured for Scarlets between 2011 and 2017 and enjoyed Pro 12 success with the club during the 2016/17 season.
The 28-year-old switched to Saracens in 2017 and was announced in December that he will head back to the Llanelli based club ahead of the 2020/21 season as the Premiership club is set to face automatic relegation at the end of the season due to salary cap breaches but now will be available for Scarlets for the remainder of this year's campaign.
Williams has played 62 Tests for Wales since his debut in 2012 but has been sidelined since returning from World Campaign in Japan last year with an injury.
“I’m really excited about returning to the Scarlets and would like to thank everyone involved for their support in making it happen,: he told the official website of the club," he told Scarlets' official website.
"I’ve had a fantastic few years at Saracens and will take some very happy memories away with me. I’ve been working hard on my recovery and can’t wait to get back on the pitch."
Scarlets head coach Brad Mooar is delighted in having the service of Williams with immediate effect.
“Liam is a world-class player and man, a huge favourite at Parc y Scarlets and we are thrilled to welcome Liam and Sophie back to the Scarlets," he said.
“To have Liam joining our exciting group of outside backs this season is superb. I’m also thrilled for Liam that his rehab is almost complete.
“Obviously, his immediate availability for us will depend on how Wayne wants to play it during the Six Nations and we look forward to seeing Liam back at Parc y Scarlets in due course.”
