New Zealand captain Kane Williamson's bowling has been deemed legal by the International Cricket Council (ICC). Williamson was reported for a suspected illegal bowling action during the first Test against Sri Lanka in August this year. <p></p> <p></p>Williamson, an offspinner, can continue bowling in international cricket as his elbow extension is within the limits of ICC regulations. "He (Williamson) subsequently underwent a bowling assessment in Loughborough on 11 October, where it was revealed that the amount of elbow extension for all his deliveries was within the 15-degree level of tolerance permitted under the ICC Illegal Bowling Regulations," the ICC said in a media release on Friday. <p></p> <p></p>This is the second time in his career that the 29-year-old has been reported for his bowling action. In 2014, he has suspended from bowling and underwent remedial process and reassessment following which he was allowed to bowl again. <p></p> <p></p>New Zealand are currently hosting England for a five-match T20I series but Williamson is sitting out after a recurring hip injury flared up. In his absence, Tim Southee is leading the side with England registering a comfortable seven-wicket win in the series opener on Friday in Christchurch. <p></p> <p></p>England, who opted to field, kept New Zealand to 153/5 before chasing down the target with nine deliveries to spare. James Vince starred for the tourists with a maiden T20I half-century.
