Pakistan all-rounder Abdul Razzaq could miss the start of the home Test series against India after being admitted to hospital in Karachi.
Razzaq provides balance to the Pakistan team
Razzaq is suffering from a severe chest infection and has less than three weeks to recover before the opening Test match in Lahore on 14 January.
"It is a terrible blow to me to fall ill just when India is due to arrive.
"I am feeling very weak and doctors say it will take time before I can resume playing cricket," he said.
"But I am keeping my fingers crossed that I am able to regain full fitness before the first Test."
Razzaq recently missed an entire Test series against England, which Pakistan won 2-0, before returning to action in the one-day internationals.
