Sri Lanka off-spinner Akila Dananjaya was reported over a suspect bowling action during the first Test at Galle, ICC said on Sunday.
"Dananjaya's bowling action will now be scrutinised further under the ICC process relating to suspected illegal bowling actions reported in Tests, ODIs and T20Is," the governing body of the sport said.
He is required to undergo testing within two weeks and during this period, Dananjaya is permitted to bowl in international cricket until the results are known, the ICC added.
The second Test against England begins on November 14 in Pallekele.
England lead the three match series 1-0.
