Will Pucovski has suffered another knock to the head while batting during Victoria's Sheffield Shield clash with Tasmania at Bellerive Oval in Hobart.

Pucovski, facing just his second ball, was struck on the side of the helmet after ducking into a rising Riley Meredith delivery on Sunday.

He immediately hit the turf as players rushed in to check on his welfare.

Pucovski spent the next several minutes on his hands and knees as medical staff attended to the 26-year-old, with the star batter coughing violently at times.

He eventually made it up on his feet and then slowly staggered off the ground to retire hurt.

The latest blow raises fresh doubts not only over his cricket career, but also his short and long-term health.

Pucovski has suffered at least 11 concussions in his career, and this latest blow seems almost certain to be diagnosed as a concussion as well.

The right-hander played his sole Test in 2021 but took time away from the game in 2022 for mental health reasons.

Just last month, Pucovski posted his first Sheffield Shield century in more than three years to spark hope that he could get his career back on track.
