Left-arm paceman Sadaf Hussain, 21, another untested player, has been included as replacement for the pacer.
Karachi: Uncapped Pakistan fast bowler Aizaz Cheema has been ruled out of this month's West Indies tour due to fitness problems.
"He has been declared unfit for cricket activities by the board doctors and has been replaced by Sadaf Hussain," a Pakistan Cricket Board spokesman said on Thursday, one day after Cheema had been named in a 16-man squad for the one-day series.
Left-arm paceman Sadaf, 21, was the top wicket-taker in the recently concluded domestic season with 64 wickets and has taken 90 wickets in just 18 first class games.
The Pakistan selectors have included four uncapped players in a new-look side for the West Indies tour.
The squad includes five players yet to play for the senior team including wicketkeeper Mohammad Salman, batsman Usman Salahuddin, allrounder Hammad Azam and pacers Sadaf and Junaid Khan.
