Test cricketer Phil Hughes suffered a sickening knock to the head from a bouncer on Tuesday afternoon and was taken from the SCG in a critical condition.
Hughes had been batting for state team South Australia and was on 63 when he was hit by the bouncer from New South Wales bowler Sean Abbott.
"For a few moments he stood, bent over head down and reeling from the blow before collapsing, face first, onto the pitch," wrote ESPN Cricinfo's Dan Brettig who was at the SCG watching the game.
NSW players, including bowler Abbott, can be seen in photos holding Hughes head still waiting for the ambulance to arrive. He was taken to St Vincent's Hospital.
The Hughes family and Cricket Australia released a statement advising the media he was now in surgery and the results of the surgery would be known within the next 24-48 hours.
