Bangladesh fast bowler Mustafizur Rahman’s hopes of gaining some valuable bowling experience in England took a huge blow after a shoulder injury ruled him out for the remainder of Sussex’s group phase matches in the Royal London One-Day Cup and NatWest T20 Blast.

Rahman is currently one of the best pacers in the world right now. However, injuries has been troubling him consistently in his small career so far. Rahman had already missed Pakistan Super League earlier this year due to a shoulder injury. After that the left-arm pacer was ruled out of the 2016 Asia Cup in February with a side strain, followed by injuries to his right hamstring and ankle, the rehabilitation of which nearly ended his Sussex stint. The same shoulder injury has resurfaced. He had an MRI scan a couple of days ago. BCB CEO Nizamuddin Chowdhury said on Wednesday that the board will decide on Rahman’s future after assessing some more medical tests.

“He has to undergo another assessment today, after which we will be able to know whether he will stay back in the UK for further medical attention or if he will return to Bangladesh,” Chowdhury told ESPNcricinfo.

The Sussex county side said in a statement that, “the 20-year-old is suffering from a shoulder injury, and, under the direction of the Bangladesh Cricket Board, is due to have a scan this week to ascertain whether or not he will be fit enough to play in any knockout matches should Sussex qualify for the latter stages of either competition”.

According to BCB’s media chairman Jalal Yunus, a fresh MRI can give the extent of the injury and the required treatment.

“He will need another MRI to understand the exact nature of his injury,” Yunus said. “There’s some extra fluid on his shoulder. The MRI will tell us what he should be doing thereafter – an injection or a surgery. We will hear the advice of the specialists in the UK and our doctors and physio.”

The pacer, who featured in two Natwest T20 Blast matches, took 4 wickets on his debut but went wicketless in the next match.
