Teenage left-hander Mehrab Hossain Junior replaced the right-hand Test batsman in the 15-member squad which will play five three-day and four limited-overs games against different English county sides.

It is the second enforced-injury change to the squad after pacer Alamgir Kabir replaced fellow seamer Anwar Hossain Munir.

Chief selector Faruque Ahmed said that they dropped Aftab as a precautionary measure.

"He strained a muscle in the left foot while in his follow through while bowling. But it is nothing serious," he informed.

"It was not wise to send him with the A team even with a slight niggle as there is the Sri Lanka tour in September and we have a chance to tour India in October and play a triangular one-day series at home thereafter," he continued.

When asked whether Aftab's injury would be used as an excuse by some other national players fatigued after spending two months in England, the former national captain dismissed the notion.

"Only Shahriar Nafees and Nafees Iqbal were in the squad all through the tour, so I don't think the fatigue or injury can be an issue rather I believe that it will be a very crucial series for all the players," he explained.

The composition of the second-string national side had earlier raised questions regarding the inclusion of so many Test caps considering nine of them had only returned from England with the senior team. Even some senior players didn't find any reason for including the 19-year-old Aftab in the junior selection.

Right-arm paceman Talha Jubair, who was also in the England Test squad but didn't play a single match, suffered an injury in his left ankle during practice at the BKSP but Faruque said that he was now okay to play the series.

"The team physio informed us that there was nothing wrong in his X-ray report and we expect to see him in the last nets on July 13," he said.

The 15-member Bangladesh A team led by left-handed opener Shahriar Nafees, who showed impressive performance in the NatWest one-day series, will leave for England on July 15.
