A place in the Super 10 phase of the World Twenty20 will be up for grabs when Bangladesh face Oman in Dharamsala on Sunday.
The final match in Group A of the initial pool stage represents a winner-takes-all affair, after Oman's meeting with Netherlands and Bangladesh's clash with Ireland each fell victim to rain this week.
Oman provided a major shock when they edged out Ireland by two wickets on Wednesday to mark their debut at a major global tournament with a stunning victory.
However, the associate nation must spring an even bigger surprise if they are to progress at the expense of a Bangladesh team that reached the final of the recent Asia Cup.
Bangladesh will look to Tamim Iqbal to maintain the excellent form that saw him strike 83 not out against Netherlands and 47 versus Ireland before rain arrived to prevent a result.
Amir Ali was the key contributor in Oman's triumph over Ireland, clubbing 32 from 17 balls to help the underdogs complete a thrilling chase.
While Oman lack star names, Bangladesh bowling coach Heath Streak insists they will not be taken lightly.
"We don't have much footage for them, but we will prepare as hard as we do for India and Pakistan," Streak is quoted as saying by ESPNCricinfo.
The winner of Sunday's match will join reigning champions India, Australia, New Zealand and Pakistan in Group 2 for the Super 10 stage. Another washout would see Bangladesh qualify on net run-rate.
