Bangladesh captain Mahmudullah Riyad won the toss and elected to bat against Oman in the opening round of the Twenty20 World Cup on Tuesday.
"Dew is a factor, that has been a consideration, but we will like to post a score on the board," said Mahmudullah.
Mohammad Naeem replaces Soumya Sarkar in a Bangladesh side that suffered a shock loss to Scotland in Sunday's Group B opener.
Oman have made one change from the side that eased past Papua New Guinea with Fayyaz Butt coming in for Khawar Ali.
Another victory for Oman would settle the group even before the final day, sending them and Scotland, who beat PNG earlier Tuesday, into next week's main event while ending Bangladesh's interest.
If Bangladesh win, there will still be a chance of three teams finishing with two wins in which case the two qualifiers will be decided on net run rate.
