London Irish have confirmed that forward Eoin Sheriff will join the club from Saracens in the summer.
The 26-year-old Irishman has made 20 appearances for Sarries since arriving at Allianz Park from Leinster in 2011.
Sheriff has previously represented Ireland at Under-20 level.
"I am really looking forward to starting at London Irish," he is quoted as saying by BBC Sport. "The facilities at the club are outstanding and their ambition for the future is clear to see. It is an exciting move and one I am relishing."
London Irish are back in Aviva Premiership action on Friday when they make the trip to Bath.
