Saracens have signed Scotland international flanker Blair Cowan on loan.
The Avvia Premiership club said 17 times-capped Cowan will be with them until the end of this season.
It follows a number of injuries in Saracens' back-row department, with the likes of Billy Vunipola, Schalk Burger, Calum Clark and Michael Rhodes all sidelined.
Cowan, 31, will head to Saracens from their Premiership rivals London Irish.
Saracens rugby director Mark McCall said: "We're very fortunate to bring in a player of Blair's experience and quality.
"He will provide great cover for the amount of injuries we have in the back-row, and we are extremely grateful to London Irish for allowing him to join us."
Cowan can be recalled by Irish at any time as part of the loan agreement.
