Pakistan's frontline fast bowler Shaheen Shah Afridi has been ruled out of next week's Asia Cup and the following Twenty20 international series against England with a knee injury, doctors said on Saturday.
The injury to the 22-year-old is a major blow to Pakistan's chances in the six-nation Asia Cup starting in the United Arab Emirates from August 27.
Shaheen's injury has already forced him to miss the second Test in Sri Lanka last month.
