New Zealand batsman and part-time off-spinner Kane Williamson has been reported for a suspected illegal bowling action during the second cricket Test against the West Indies in Trinidad.

Umpires Ian Gould, Richard Illingworth and Rod Tucker, and match referee Chris Broad told New Zealand management they were concerned about a number of Williamson’s deliveries they considered to be suspect and believe his action needs to be tested.

Williamson bowled nearly 16 overs for one wicket in the second Test in Port of Spain, which the West Indies won by 10 wickets.

His bowling action will now need to be tested within 21 days but he can continue to bowl in international cricket until the results are known.

The third and deciding Test match starts in Barbados on Thursday, local time.
