Saracens have agreed the signing of South African back-row forward Michael Rhodes from Super 15 side Stormers.
The 27-year-old, who can play at flanker or lock, will join Sarries at the beginning of next season.
"Michael was one of the stand-out performers for the Stormers and Western Province last year," said Saracens director of rugby Mark McCall.
"He's a powerful runner with the ball in hand and he's an imposing presence at the set-piece."
Rhodes started his professional career with the Sharks in Durban, and played for the Lions before joining the Stormers.
