Mohammad Hafeez will lead Pakistan in their second one-day international with Australia after Azhar Ali was ruled out through injury, the Pakistan Cricket Board has confirmed.
Regular ODI skipper Azhar hurt his hamstring during Friday's opening ODI in Brisbane, which Australia won by 92 runs.
He is sure to miss Sunday's contest in Melbourne and is also expected to sit out the third ODI in Perth before hopefully returning for the last two matches of the series.
With vice-captain Sarfraz Ahmed also unavailable after leaving the tour to be with his ill mother, Pakistan have turned to the experienced Hafeez, 36, as leader.
Hafeez has previously served as his country's Twenty20 skipper and also captained Pakistan in a solitary Test five years ago.
He was not part of Pakistan's initial ODI squad for the Australia tour, but was added to the party last week.
