Bangladesh Cricket Board confirmed the development in a statement on Saturday citing “Tamim’s family reasons”.
BCB already included Imrul Kayes in the squad as Tamim’s replacement after the batsman had informed the board about the matter.
Tamim will fly to Bangkok to be with his wife Ayesha Siddiqa Iqbal after two or three days and likely to be with her for at least two to three weeks.
The couple’s first child was born at a hospital in Thailand in February 2016.
