The loss of Pattinson is the second blow suffered by Australia's pace attack in less than 24 hours, with Mitchell Starc also ruled out, having failed to recover fully from a long-term foot injury. Legspinner Mitchell Swepson replaced Starc in the squad.
Pat Cummins, Josh Hazlewood and Bird are now the only three frontline pace bowlers in Australia's squad. The Boxing Day Test against Pakistan at the MCG last December was Bird's last Test appearance. He was part of Australia's squad on their tour of India in February-March, but did not get to play a Test.
Australia will start their tour with a two-day warm-up game in Fatullah on August 22 and 23. The first of two Tests starts in Mirpur on August 27. After months of doubt over whether it would go ahead or not, the tour got its green signal following the resolution of the contracts dispute between Cricket Australia and the Australian Cricketers' Association.
Australia squad: Steven Smith (capt), David Warner (vice-capt), Ashton Agar, Hilton Cartwright, Pat Cummins, Peter Handscomb, Matthew Wade (wk), Josh Hazlewood, Usman Khawaja, Nathan Lyon, Glenn Maxwell, Matt Renshaw, Mitchell Swepson, Jackson Bird.
