West Indies off-spinner Shane Shillingford has been reported for a suspected illegal bowling action during the first Test against Sri Lanka in Galle.
The 27-year-old took five wickets in the match - which ended in a draw on Friday - returning figures of 4-123 and 1-79 during the hosts' two innings.
He was reported to the International Cricket Council by on-field umpires Steve Davis and Richard Kettlebrough, as well as TV umpire Asad Rauf and fourth umpire Tyron Wijewardene.
Shillingford must now undergo tests to analyse his bowling action within the next 21 days.
If his action is found to be illegal, he will be suspended until he can show that he has made the necessary adjustments.
