Saracens have announced the signing of Australian international lock Will Skelton on a short-term deal.
The towering forward made two appearances during Australia's recent Spring Tour going on as a replacement against Scotland and France.
Skelton, 24, will move to Saracens with immediate effect from the Waratahs, bolstering the club's second-row department following the recent retirement of Alistair Hargreaves.
"We are delighted to be able to bring a player of Will's calibre into the group," said Saracens rugby director Mark McCall.
"He is an immensely-talented rugby player with vast experience for a 24-year old tight-five forward.
"It's no secret that we have been running low on a few bodies in the second-row department, but we made it very clear that we wouldn't compromise on quality when looking to add to our squad.
"In Will, we have a player who will certainly have an important role to play in our group over the next few months."
It is understood Skelton will be back in Australia in time for the start of the Super Rugby season but is unlikely to be available to play in any of the Waratahs’ pre-season fixtures.
Skelton’s situation differs from the short-term release of Reds backrower Leroy Houston late last year, who went to Bath on a medical joker contract.
