Prop Juan Figallo has agreed a contract extension with Saracens.
The Aviva Premiership club announced that 30-year-old Figallo's deal will keep him at Allianz Park until the summer of 2021.
Saracens rugby director Mark McCall said: "We're very pleased Juan has committed his future to Saracens.
"He has contributed enormously on and off the pitch in his four years at the club. He's a great player, a brilliant character."
The Argentina international, who has won 24 caps, joined Saracens from French Top 14 side Montpellier four seasons ago and is happy to extend his stay.
"I'm really happy to stay," Figallo said. "I've played four seasons here and I've really enjoyed myself.
"My family came here as two; I got married just before I came here and now we have two kids and we're living the Sarries life. We really love it."
