The third T20I has been added following discussions between the Emirates Cricket Board and the Bangladesh Cricket Board (BCB).
It will begin at 7:00pm local time, just like the second match of the series scheduled for today (Monday), also at Sharjah.
Originally, the two teams were set to play a two-match series, but the addition of a third match offers both sides more game time ahead of their future international commitments.
Bangladesh won the opening match of the series by 27 runs on Friday, thanks to a stunning century by Parvez Hossain Emon.
Broadcast of the series will be available globally, including T-Sports in Bangladesh, Fancode in India, Cricbuzz across MENA, Geo Super in Pakistan, Willow TV in the US and Canada, and Sportseye/YouTube, reports UNB.
