He needed attention from the team physio and then continued batting before being out on 81 off 123. <p></p> <p></p>However, he complained of headache after waking up on Friday following which he was taken to the hospital. He didn't take field on Day 4 and Mohammad Rizwan has taken the wicketkeeping duties. Asad Shafiq is leading Pakistan in his absence. <p></p>Meanwhile, Usman Khawaja faces the prospect of missing the start of Australia s home Test series with India from December 6 with surgery the likely requirement for a meniscal tear on his left knee. <p></p> <p></p>The batsman twisted his left knee during throw-downs before the start of day three and will meet a knee surgeon upon return to Australia. If he undergoes surgery, Khawaja could be sidelined for anywhere between six weeks to three months.
