A knee injury has seen Fakhar Zaman miss out on Pakistan's squad for the 2022 T20 World Cup, while Shan Masood, who is yet to play a T20I, has been called up.
Fakhar was named as one of the travelling reserves, though, along with Mohammad Haris and Shahnawaz Dahani.
Shaheen Shah Afridi, who is currently sidelined with a knee injury, was named in the main squad as Pakistan look to get him fit in time for the global event. Mohammad Hasnain, meanwhile, edged out Dahani.
There were no wholesale changes to the side that played the Asia Cup earlier this month. Usman Qadir kept his place despite playing just one match in the tournament and limited match-time prior to it.
Afridi and Fakhar were also absent from the 18-member roster for the upcoming seven-match T20I series against England.
"Fakhar Zaman has also been rested from the England T20Is so that he can recover from the knee injury he sustained when he landed awkwardly while fielding in the final [of the Asia Cup]," chief selector Mohammad Wasim said.
A PCB release stated: "Afridi is expected to resume bowling early next month and will join the squad in Brisbane on October 15. Wasim Jr has been included after recovering completely from the side strain he suffered during the Asia Cup."
Changes can be made to the squad till October 15, without needing the approval of the World Cup's technical committee.
Masood is part of the squad for the England series as well, while allrounder Aamer Jamal and legspinner Abrar Ahmed have received maiden international call-ups. Both impressed in the ongoing National T20 Cup. The first match of the series is on September 20 in Karachi, which will host four games in total before the series moves to Lahore for the final three matches.
After the England series, the team will head to New Zealand, where they play a T20I tri-series against New Zealand and Bangladesh in Christchurch from October 7-14.
Pakistan play their first World Cup match against India at the MCG on October 23. They will also play New Zealand, Afghanistan and two qualifiers in the group stage before the top two sides go to the semi-finals.
