Bangladesh pair Arafat Sunny and Taskin Ahmed have both been suspended from bowling by the International Cricket Council for having illegal actions.
Left-arm spinner Arafat, 29, and pace bowler Taskin, 20, took two wickets apiece in Bangladesh's opening Super 10 defeat by Pakistan and have played in all four World Twenty20 matches.
The Tigers will be permitted to name replacements in their squad.
