Glasgow Warriors and Canada winger DTH van der Merwe will miss the rest of the current season thanks to a shoulder injury.
The flyer has undergone surgery and will be out of action for up to six months.
Last week Scotland international Lee Jones joined the club on loan until the end of the season to provide cover.
"We're really disappointed for DTH that he's going to be out for the rest of the season," said Warriors head coach Gregor Townsend.
"He has been an important player for the club over the past few seasons and we wish him well in his recovery.
"We brought in Lee (Jones) last week to provide cover until the end of the season and we were delighted with his display on his debut against Connacht."
