Aviva Premiership leaders Saracens have signed Scotland second-row Kieran Low on loan from Glasgow Warriors until the end of the season.
The 24-year-old joined the Pro12 champions in the summer but made the last of his three appearances for the club in October.
Low has Premiership experience having played 43 times for London Irish.
"We are delighted to be able to bring in a player of Kieran's calibre at this point of the season," said Saracens director of rugby Mark McCall.
"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."
Low, who has five international caps, will link up with Saracens ahead of Saturday's top-of-the-table clash with Leicester Tigers.
Glasgow head coach Gregor Townsend said: "This is a good opportunity for Kieran to get game time in the Aviva Premiership and we wish him all the best at Saracens."
