Warriors have signed 26-year-old Canada fly-half Connor Braid until the end of the season.
Braid has been capped 21 times by his country, with his latest coming last weekend in Canada's clash with Romania.
Head Coach Carl Hogg said: "With recent injuries to Ryan Lamb and Tom Heathcote, we're delighted Connor is able to come in and bolster the side in the number ten position.
"He has plenty of experience in goal-kicking while his versatility across the backline will also be of great benefit.”
The versatile back, who can also play in the centre or the back three, will join up with the squad following Canada's match with Samoa on Friday.
