Pakistan have been hit by a second series-ending withdrawal in as many days, with spinner Noman Ali suffering from appendicitis.
Ali, who didn't play in the first Test in Perth, will miss the rest of the series in Australia after undergoing surgery in Melbourne on Saturday.
"Noman Ali complained of sudden and severe abdominal pain yesterday, leading to examinations and scans in emergency that confirmed a diagnosis of acute appendicitis," a Pakistan team statement read.
