Sale have signed Argentine full-back Joaquin Tuculet on a one-year contract.
The 22-year-old joins from Los Pampas, and recently scored four tries in four matches for the Argentina 'A' side at this summer's IRB Nations Cup.
Sharks director of sport Steve Diamond said: "I first saw Joaquin when I coached Russia and he impressed me.
"He narrowly missed out on the Pumas' World Cup squad, and I am delighted he's joined us. He'll fit in perfectly with what we are trying to achieve."
