Pakistan spinner Noman Ali was recovering Saturday after being rushed to hospital with acute appendicitis, with the veteran ruled out of the rest of their series against Australia.
The 37-year-old, who did not feature during a heavy defeat in the opening Test in Perth, suffered severe abdominal pain on Friday.
"Noman Ali complained of sudden and severe abdominal pain yesterday, leading to examinations and scans in emergency that confirmed a diagnosis of acute appendicitis," the Pakistan Cricket Board said.
