Bangladesh fast bowler Al-Amin Hossain has been reported to the International Cricket Council (ICC) for a suspect action.
Al-Amin was reported by match officials following Bangladesh's 10-wicket loss to West Indies in the first Test in St Lucia that came to an end on Tuesday.
The 24-year-old follows team-mate and off-spinner Sohag Gazi in becoming the second Bangladesh player in less than two weeks to have his action reported to the sport's governing body.
Sohag was reported following a one-day international clash with the West Indies on August 24.
Al-Amin will now have his action tested at an ICC facility in either Brisbane or Cardiff, and he can continue bowling until the results of those examinations are revealed.
An ICC statement read: "The match officials' report, which was handed over to Bangladesh team manager Habibul Bashar after the Test concluded on Tuesday, cited concerns about the legality of the 24-year-old's bowling action.
"Al-Amin's bowling action will now be scrutinised further under the ICC process relating to suspected illegal bowling actions reported in Tests, ODIs and T20Is.
"He is required to undergo testing within 21 days, and, during this period, Al-Amin is permitted to continue bowling in international cricket until the results of the testing are known."
In a recent crackdown by the ICC, Sri Lanka off-spinner Sachithra Senanayake, New Zealand's Kane Williamson, Zimbabwe's Prosper Utseya and Pakistan's Saeed Ajmal have been reported, with Senanayake, Williamson and Ajmal banned from bowling as a result.
