Hooker Jack Singleton will make a return to Saracens from Gallagher Premiership rivals Worcester Warriors ahead of the 2019/20 season.
Singleton was part of the Saracens Academy since 2014 and made his debut for Worcester Warriors in 2016 making close to 50 Premiership appearances for the Sixways outfit since then. The 22-year-old went on to win the Club's Young Player of the Season for the 2016/17 season.
His performances for Worcester saw him involved in the England squad that went on to take on Barbarians in May 2017 and was also added to the Eddie Jones' squad for the red rose team's tour of South Africa after the first Test in the summer series last year.
"I'd like to thank Worcester for an incredible five years.
"They gave me the chance to progress as a player and have helped me develop immensely in that period. I'm extremely grateful to them".
Singleton will replace Christopher Tolofua in the Saracens squad with the France international set to move to Toulon next season.
"We're pleased to have signed a player of Jack's quality; someone who knows the club well, having been in our academy," said Saracens director of rugby Mark McCall.
"He has significantly progressed his rugby with Worcester and we are excited to see what more is to come."
