Scotland international second-row Kieran Low has joined Premiership side Saracens until the end of the season.
He will be registered with Saracens from Friday (January 1).
The 24-year-old, who joined the club this year, has played three times for the Warriors but has not featured since early October.
Glasgow Warriors head coach Gregor Townsend said: "This is a good opportunity for Kieran to get game time in the Premiership and we wish him all the best at Saracens."
Saracens director of rugby, Mark McCall: “We are delighted to be able to bring in a player of Kieran’s calibre at this point of the season. He is an international quality lock forward who has plenty of Premiership experience.
"With a few injuries and the expectancy that we will lose a few second row forwards during the Six Nations we are very happy to be able to bring Kieran into the group.”
