Taskin ruled out of the only Test against Ireland
Taskin himself confirmed the news to The Business Standard (TBS).

Bangladesh pace spearhead Taskin Ahmed has been in a great run of form for Bangladesh. He picked up 13 wickets in total in the recently concluded white ball series against Ireland. The pacer was rearing to play the only Test against Ireland but he received a sad news on his birthday just the day before the match.
The 28-year-old, who has been playing continuous cricket for the past few months, is set to miss the only Test starting from Tuesday due to a side strain. Taskin himself confirmed the news to The Business Standard (TBS).
He picked up the injury during the T20I series against Ireland.
The Bangladesh Cricket Board (BCB) hasn't announced any replacement for Taskin yet.
Rezaur Rahman Raja may be included in the squad in place of Taskin. According to BCB's medical department, Tasikon will need at least two weeks to recover from the side strain injury.
The in-form Taskin could not finish the BPL due to injury. He did not play in the last few matches of Dhaka Dominators keeping in mind the England series. He played two ODIs against England after being fit, and played in all the matches of the pacers' next three series.
But he now has to go to be in the audience's seat during his favorite Test format.
