Bangladesh survived a dramatic final over to pull off a narrow three-run win against Zimbabwe in T20 World Cup, where the officials, in a rare incident, called the players back from dug out to complete the contest after realising that Nurul Hasan's stumping in the final ball was not clean, here Sunday.

Bangladeshi players were celebrating after Zimbabwe's Blessing Muzarabani, who was required to hit a six in the final ball for a famous win, missed the ball and was stumped by Nurul Hasan.

However TV replays showed that Hasan had collected the ball in front of the wicket, which is against the rules, hence Zimbabwe were awarded a free hit and all the players were called back for final action.

Zimbabwe now needed four runs to win.

The nonplussed players, who had walked off the field after shaking hands, thinking that Bangladesh had won, assembled again.

Zimbabwe could not cash in on the chance and no further drama followed as Muzarabani again missed the ball again and finally Bangladesh rejoiced the victory.

Zimbabwe were chasing 151 and fell short by three runs.

It was opener Najmul Hossain Shanto who smashed seven fours and one maximum in his 55-ball 71-run knock and single-handedly powered Bangladesh to a competitive 150 for 7.

In reply, Zimbabwe lost too many wickets to find themselves in the dumps at 35 for 4 in the sixth over but Sean Williams conjured up a magnificent 42-ball 64-run innings to revive the chase.

He was dismissed in the 19th over, leaving Zimbabwe to get 16 in the last six balls.

Hossain then bowled the most important over of his career as he dismissed Brad Evans (2) in the second ball but Richard Ngarava slammed him for a four and a six in the next two balls to keep them in the hunt.

Hossain, however, had Ngarava stumped in the next ball as Zimbabwe needed five off the last ball.

The unprecedented scenes followed after that but eventually Bangladesh survived.
