Pucovski was struck by the short ball from the second delivery he faced and immediately went down on his knees in the crease. The Cricket Australia doctor and Victoria physio were quickly into the middle but after some time to compose himself Pucovski was able to walk off the field unaided for further assessment.

Campbell Kellaway was brought into the XI as the concussion substitute. The match is in the fourth innings with Victoria chasing 442.

"Pucovski, who walked from the field, is being monitored by medical staff," a Cricket Victoria statement said. "More information will be provided at a later stage."

Pucovski has suffered multiple concussions throughout his career and last month returned from another spell on the sidelines where he made a century against New South Wales at the SCG.

He has also had time away from the game for his mental health and earlier this year spoke about he has learnt that there is a link between that and his concussions.

"I sort of link the mental health stuff back to my first concussion...which was when I was about 15 or 16," Pucovski he told the Vic State Cricket podcast. "I have a lot of concussion symptoms that over a seven or eight year period, actually never subsided.

"You just sort of got used to having them in a way. The brain's pretty amazing and can find ways to adapt. I would fail concussion tests in the exact same way every single time, regardless of whether I had been hit in the head, and that was over a seven or eight year period."

"The mental health has been a much bigger issue for me than even the concussions," he added. "I don't fear for my long-term health, it's more the mental health side that's been the tougher part."

"One day I'll be ready to tell my whole story and it will probably make a lot more sense. I've explained what I've been through to my inner circle of people and actually all the responses I've got have been like 'Jesus, I would never have guessed that in a million years, that doesn't even make sense to me'.

"It hasn't made sense to me for years, either, but I've been on this pathway to understand it all."

Pucovski played one Test for Australia in early 2021, against India at the SCG.
