"Hafeez has a calf muscle injury and doctors say he requires two to three weeks to make a complete recovery," a spokesman of the Pakistan Cricket Board told PTI.
"The tour selection committee has sent in a request to the board Chairman to allow them to replace Hafeez with opener, Nasir Jamshed," media manager Raza Kitchlew said.
"A request with medical reports has been dispatched to the ICC technical committee to allow this replacement," he added.
Although he is presently suspended from bowling in international cricket by the ICC due to an illegal bowling action, he was picked in the World Cup squad by the selectors for his batting ability alone.

Hafeez was due to appear in a ICC official bowling reassessment in Brisbane on February 16 but the PCB is now contemplating asking the ICC to extend the date until the all-rounder makes a full recovery from his injury.
He said that the decision of replacements was with the tour selection committee but the final approval came from the board Chairman Shaharyar Khan.
