Michael Cheika is hopeful David Pocock will be fit for next week''s clash with England after the talismanic back-rower left the field early in the Wallabies' win over Italy in Padova.
It was thought Pocock had sustained a concussion which due to the HIA protocols would have put him in serious doubt for the season finale against Eddie Jones' side.
However, Cheika said Pocock had instead suffered a stinger in his left arm after being pinned down at the bottom of a ruck in the 26-7 win at the Stadio Euganeo.
"He's obviously got a pretty nasty stinger on his neck," Cheika said.
"It was giving him the burns down the arm for quite a while. We'll just wait and see what happens and see how he recovers over the next couple of days."
The win was another excellent defensive display from Cheika's men, who have now given up 16 points in two games, against a desperate Italian side who dominated large spells of possession in either half.
Scott Sio's yellow card for a deliberate knock-on during a sustained spell of second-half pressure from the home side when the score was 21-7 was a severe test for the tourists.
But they held strong and were able to come through and ice the game thanks to Will Genia's late try.
"We stuck solid, even when we had penalty advantages against us, we stayed at them," Cheika said.
"We didn't want to let them over the line. We were a little bit disappointed with how we gave up the try.
"We could've been off the back of two games without a try being scored against us.
"(It's) something we've been focusing on as a team to improve.
"Even there where it's really quite tight you've got to fight hard and I thought we fought very hard down there. Then we lost a player and we were able to resist as well."
