Western Australia captain Adam Voges has suffered concussion after being struck on the helmet during a Sheffield Shield match against Tasmania at the WACA.
Voges has been ruled out of the rest of the match after retiring hurt on 16 when he failed to evade a bouncer from fast bowler Cameron Stevenson and was hit on the helmet.
Voges lay on the ground for some time after the blow, and was assisted from the ground by medical staff before being monitored in the change-rooms.
Earlier this year, Voges suffered a freak head injury while playing county cricket for Middlesex, when he was fielding at slip and was hit on the back of the head by a ball being thrown back towards the wicketkeeper after a boundary.
After his failures in the first two Tests against South Africa, Voges loomed as a likely candidate to be axed for the third Test in Adelaide, and was hoping for a big innings against Tasmania to press his case for retention.
