Argentina international Juan Martin Gonzalez has signed a new “long-term” contract with Saracens.
The 23-year-old flanker has made 11 appearances since joining the club from London Irish last summer.
He has has scored nine tries in 31 international caps for Argentina.
Former captain Owen Farrell will leave Saracens for Racing 92 at the end of the season, while England internationals Maro Itoje and Elliot Daly have also signed new deals.
“I am very proud and happy to stay longer in this beautiful club,” Gonzalez said.
“The truth is that I needed stability and there is no better place to be than Saracens.”
Gonzalez began his career in Buenos Aires at Jaguares before moving to London Irish in 2021.
He made 36 appearances for the Exiles, scoring eight tries, before the club was excluded from playing competitive rugby in the 2023-24 season because of unpaid taxes.
The back row subsequently moved to Saracens, scoring six tries this season as they sit fourth in the Premiership, one point behind second-placed Harlequins.
