Sale Sharks have signed fly-half Robert du Preez on a three-month deal from South African side the Sharks.
The 25-year-old, who has one South Africa cap, helped his side win the Currie Cup at the weekend.
"Rob comes with an outstanding CV and will be a fantastic injury replacement for AJ MacGinty," said Sale director of rugby Steve Diamond.
United States fly-half McGinty will miss the rest of 2018 because of a shoulder injury.
Sale are 11th in the Premiership with two wins from six games.
