Pakistan captain hopes Shahid Afridi will recover in time for the tournament after suffering a groin injury
Afridi played in the Asia Cup final on Saturday (March 15) with painkillers after hurting his groin during Pakistan's victories against India and Bangladesh with some powerful late hitting last week.
"As a captain I need a fit Afridi, and that's why we have given him time to rehab," said Hafeez.
Pakistan leaves for Dhaka on Thursday, and manager Zakir Khan says they hope Afridi can join the team on Monday.
Pakistan's first group match is against India on March 21, and Hafeez says he's happy to open the World Twenty20 with a pressure match against the archrivals.
