Waratahs hooker Tatafu Polota-Nau is returning to Leicester after two appearances for NSW on loan.
Polota-Nau joined the Waratahs ahead of their clash with the Reds a fortnight ago, with NSW short on fit forwards.
At the time Leicester said the rake would be back in England by the end of the month and he has duly returned to the UK this week.
His loan was a short-term injury cover deal between the two clubs and Polota-Nau ultimately played just an hour of football for the Waratahs before being asked to return.
Prop Shambeckler Vui is the frame to be fit for Saturday's Crusaders match while rookie hooker Andrew Tuala would be the first-choice to back up starting hooker Damien Fitzpatrick with Tolu Latu still missing through suspension.
Waratahs coach Daryl Gibson said Polota-Nau had stepped into the club easily, praising his contirbution during his short time in Sydney.
“Our team is very grateful to Tatafu and Leicester Tigers for helping us fill a short term injury cover," he said.
“We entered a loan arrangement always knowing Leicester would want him back in England in the near future.
“Tatafu slotted back into the squad with such ease and was a big contributor for the squad. It also gave Tatafu the chance to show Aussie selectors how he’s progressing ahead of the World Cup.
“Shambeckler Vui is working his way back to full fitness and Andrew Tuala will also come into the squad. Tuala had two great games with our Emerging Waratahs side and has been working hard at our training sessions."
The Waratahs take on the Crusaders on Saturday night, kicking off at 7:45pm AEDT, LIVE on FOX SPORTS and via RUGBY.com.au RADIO. Buy tickets here.
