Saracens have signed former Waratahs hooker Dave Porecki as cover for the World Cup.
The 22-year-old Australian front-rower, who has been playing for Manly Marlins Rugby in Sydney, has joined the north London club on a short-term contract.
"With Jamie George and Schalk Brits potentially away with England and South Africa for the World Cup we felt that we needed some more depth in the hooking position," said Saracens director of rugby Mark McCall.
"Alongside Scott Spurling and Jared Saunders, Dave will provide us with more options. He has been training with us since we returned to pre-season and has fitted into the club very well.”
Porecki said: "All the boys have been very welcoming since I've arrived and the coaching staff have been great with me. It's a great opportunity and one I'm looking forward to making the most of.”
