Waqar has already resigned, but agreed to stay on for the Test beginning on Thursday, three one-day internationals and two Twenty20 games in Zimbabwe, Pakistan's first tour to the African nation in nine years.
The former fast bowler's departure is the latest of regular upheavals for Pakistan since a spot-fixing controversy in England a year ago. Expected to win, Pakistan's real Test in Zimbabwe will be to finally find some unity and stability.
It could try out inexperienced batsman Rameez Raja and bowlers Yasir Shah, Sohail Khan, Junaid Khan and Aizaz Cheema alongside the experience of captain Misbah-ul-Haq, Younis Khan, Saeed Ajmal and recalled former Test skipper Shoaib Malik - who traveled with the squad after being cleared of financial misconduct. Bowlers Umar Gul, Wahib Riaz and Abdur Rehman were all rested.
Zimbabwe have had their own problems and was out of Tests for six years following a player-board dispute which brought the game in the troubled African country to its knees.
