Australia Test batsman Adam Voges has been ruled out for the remainder of Western Australia's Sheffield Shield match due to concussion after being struck on the helmet.
In concerning scenes in Perth on Thursday, Voges had to be assisted from the WACA Ground after he was hit in the head by a bouncer during a clash against Tasmania.
Voges was 16 not out when he was struck following a delivery from bowler Cameron Stevenson, dropping to the ground before he was treated by medical staff.
It is the second time this year that Voges has been hit in the head while playing cricket.
In May, Voges was struck on the back of his head while fielding for Middlesex in a County Championship game against Hampshire.
It is also a blow for the 37-year-old in his bid to retain his Test spot, with Australia reeling from their embarrassing defeat to South Africa in Hobart.
Voges managed just scores of zero and two as Australia suffered an innings and 80-run defeat to the Proteas, who claimed an unassailable 2-0 series lead.
