Saracens have confirmed that France hooker Christopher Tolofua will join the club on a two-year deal from the beginning of next season.
The Toulouse front-rower will head to north London after the completion of the 2016/17 Top 14 season.
On signing for Saracens, 22-year-old Tolofua said: "I have spent a long time at Stade Toulousain, so joining another squad is a very big move for me and I know I could not find a better team than the Saracens.
"I'm excited to play in England next season and test myself in the Aviva Premiership. I think it's the experience I need to take my rugby to the next stage, whilst serving my best for Sarries."
He added: "The recent past of the Saracens speaks for itself and I am very proud to be joining such a good club with great coaches and great team-mates."
