New Zealand captain Kane Williamson's bowling action is legal again, the ICC confirmed, following an assessment in Loughborough on October 11.

Williamson had been reported during the Galle Test in August earlier this year. He bowled three overs of offspin in that game, conceding nine runs without taking a wicket. But now, following a test in an ICC-accredited bio-mechanics centre, it was found that the elbow extension of all his deliveries was within the permissible 15-degree level of tolerance.

This was the second time that Williamson's bowling action had come under scrutiny. He was reported in 2014 and had to make some changes before he could bowl in international cricket again.

Williamson is currently nursing a hip injury that had sidelined him from the ongoing five-match T20I series at home against England but, with the ICC clearing his action, he can bowl again when he returns to play for New Zealand.
