Nasir Jamshed will replace Mohammad Hafeez who is suffering from a calf injury
Hafeez is suffering from a calf injury, which he picked up while batting in the second ODI against New Zealand in Napier on 3 February.
Nasir, the 25-year-old left-handed opener, has played 45 ODIs for Pakistan in which he has scored 1,413 runs with three centuries and eight half-centuries. His last ODI was against New Zealand in Abu Dhabi in December 2014.
Any injury or illness-based replacement requires a written submission to the Event Technical Committee along with a diagnosis from a medical practitioner as to the extent of the injury or illness. Once replaced, a player may not return to the squad save as an approved subsequent replacement for another injured or ill player.
The Event Technical Committee of the ICC Cricket World Cup 2015 is Geoff Allardice (ICC General Manager – Cricket, Chairman), Campbell Jamieson (ICC General Manager – Commercial), John Harnden (Chief Executive, CWC 2015 LOC), Gavin Larsen (Cricket Operations Manager, New Zealand), Russel Arnold and Sanjay Manjrekar (independent nominees).
Pakistan is in Pool B of the ICC Cricket World Cup 2015 along with defending champion India, former winner the West Indies, African rivals South Africa and Zimbabwe, and qualifiers Ireland and United Arab Emirates (UAE). Pakistan will play its opening match against India at the Adelaide Oval on 15 February.
