West Indies spinner Shane Shillingford has been reported for a suspected illegal bowling action following the opening Test against Sri Lanka, the International Cricket Council (ICC) said on Saturday.
Off-spinner Shillingford, playing only his fourth Test, bagged five wickets in the first match, which ended in a draw in Galle.
The umpires' report has cited concern over the straightening of Shillingford's arm while bowling some deliveries to the degree that may constitute an illegal action, according to an ICC press release.
"Shillingford's bowling action will now be scrutinised further under the ICC process," the release said.
The spinner will now have to submit to an independent analysis of his bowling action, which will be conducted by a member of the ICC panel of human movement specialists.
"This analysis and report must take place within 21 days of the report being received by the WICB [West Indies Cricket Board]," said the ICC release.
"If the player is found to have bowled with an illegal action during the independent analysis then he will be suspended from bowling in international cricket until he undertakes remedial action and is reassessed."
Shillingford will be permitted to continue bowling in international cricket till then, meaning he is available for the second Test starting in Colombo on Tuesday.
