Saracens have completed the signing of South African flanker Nick Fenton-Wells for next season.
The 25-year-old from Cape Town, who plays for Stormers and Western Province, is the club's second signing this week following Italian prop Lorenzo Romano.
"We have been following Nick's progress for some time," Saracens rugby director Mark McCall told the club's website.
"He has the heart of a lion and we are delighted he has decided to join us."
Fenton-Wells will arrive at Vicarage Road next month.
He said: "Everybody in SA rugby follows what is happening at Saracens, and I'm looking forward to joining a club that continues to break new ground in so many ways."
