Low joins Saracens on loan

The 24-year-old joined the Celtic League champions in the summer but made the last of his three appearances for the club in October.

"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 London Irish]. 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.

"This is a good opportunity for Kieran to get game time in the Premiership and we wish him all the best at Saracens," Glasgow Warriors head coach Gregor Townsend said.
