Bangladesh trainer David Dwyer has stepped down from his position after 14 months on the job. Akram Khan, the BCB’s Cricket Operations Committee Chairman, confirmed the receipt of the resignation letter two days ago.Dwyer is understood to have asked for immediate release. He joined Bangladesh as the head of strength and conditioning in February last year, a week before the team left on a tour of Sri Lanka. Like the rest of the coaching staff, Dwyer’s contract was due to expire after the 2015 World Cup.”He has done a great job for the Bangladesh team,” Akram said. “It is up to the board to accept his resignation, but I think we have to start looking for a new trainer immediately. We have a lot of cricket ahead.”Bangladesh’s next assignment is a three-match ODI series against India in mid-June. The tour schedule, however, hasn’t been confirmed.
