Will Pucovski's hopes of a Test debut are in serious doubt after he copped a blow to the head in Australia A's drawn tour match against the Indians.
Pucovski, who has had eight concussions previously, was hit on the front of the helmet trying to pull a ball from paceman Kartik Tyagi.
On 23 at the time, he remained on his hands and knees on the ground for around 90 seconds before being escorted from the field retired hurt.
He looked dazed as he walked from the ground unassisted, with Dr John Orchard beside him.
However, he was not taken from the ground in an ambulance and it's believed he was up and talking in the dressing room after play.
The young gun looked to be closing in on a debut after double centuries in both Sheffield Shield games for Victoria this summer.
The blow came at the worst possible time for him and Australia, with selectors dealt the tough task of creating new plans for a first Test just nine days away.
David Warner remains in grave doubt and in a race against time to beat a groin injury, initially opening the door for incumbent Joe Burns and Pucovski to open.
Burns himself is in a poor run of form, bowled for a duck in Australia's brief 15-over second innings that finished at 1-52.
The Queenslander has passed 11 just once in seven innings this summer, with his average sitting at 8.71.
Marcus Harris, originally left out of the Test squad, has now firmed for a recall.
He finished 25 not out on Tuesday, and started the season with a double century.
Cameron Green also did his Test chances no harm, taking two wickets on Tuesday to go with his unbeaten 125.
He removed openers Prithvi Shaw (19) and Shubman Gill (29) with his pace and bounce - both caught at point - to return figures of 2-19.
The 21-year-old still faces a tough task to crack into Australia's Test team for the series opener next week, with selectors keen to stick with the incumbent middle order.
Queensland quick Mark Steketee meanwhile took 5-37 in India's second innings before they declared at 9-189 and set Australia A 131 from 15 overs.
Michael Neser claimed 2-41, including the prized scalp of Cheteshwar Pujara for a duck when he took his off stump with one that seamed back at him.
