New Zealand off-spinner must undergo testing within 21 days
Williamson was reported at the end of the match by umpires Ian Gould, Richard Illingworth and Rod Tucker, all from the Emirates Elite Panel of ICC Umpires, as well as Chris Broad of the Emirates Elite Panel of ICC Match Referees.
Mr Broad handed over the copy of the report to the New Zealand team manager on Friday.
The umpires’ report cited concerns over a number of deliveries that they considered to be suspect and believed that his action needed to be tested.
Williamson’s bowling action will now be scrutinised further under the ICC process relating to bowlers reported in Tests, ODIs and T20Is. The off-spinner is required to undergo testing within 21 days, and, during this period, he is permitted to continue bowling in international cricket until the results of the testing are known.
