Pakistani all-rounder Abdul Razzaq has been admitted to hospital with a severe chest infection and is doubtful for the start of the home series against India next month.
Razzaq missed the recent Test series against England due to an elbow injury but returned to the side for the one-day internationals.
"It is a terrible blow to me to fall ill at this time just when India is due to arrive in Pakistan," Razzaq said on Wednesday.
"I am feeling very weak and doctors say It will take time before I can resume playing cricket. But I am keeping my fingers crossed that I am able to regain full fitness before the first test against India."
India arrive in Pakistan on January 5 to play three Tests and five one-day internationals.
The first Test starts on January 13 in Lahore.
Razzaq has played 37 tests and 201 one-day internationals.
