YORKSHIRE overseas star Kane Williamson is determined to remain positive about his future as a bowler after his action was deemed illegal last week.

The New Zealand international batsman, who has bowled some useful part-time off-spin through his domestic and international career, was banned from bowling in all cricket after tests at Cardiff University.

Bowlers are allowed 15 degrees of flex in their elbow but Williamson has exceeded that and must work on remodelling his action and get retested before he can start bowling again competitively.

The 23-year-old Kiwi says there has been extensive dialogue between himself, Yorkshire and his New Zealand coaches and they are happy for him to continue his remedial work in England while completing his county commitments.

Ahead of today's Royal London One-Day Cup clash with Gloucestershire – Williamson's former county – at Headingley, he said: "Although it's not ideal, there are worse things in life.

"Hopefully I can use it to my advantage as it means I have to put a bit more time into my bowling, because I never really have before. I've just bowled in the nets and perhaps that's where my action's lost its way a little bit.

"Although I don't bowl a huge amount, I do enjoy my bowling. I want to get back bowling and that's going to require a bit of work.

"There's no specific timescale on it just yet (getting retested) but I'll be working to try and get it done as soon as I can.

"New Zealand are good with the situation. I've been in touch with them a lot recently and liaised with various coaches here too about trying to change a few things.

"There's no real rush but I do want to get back and be effective with the ball."

Williamson top-scored in Yorkshire's opening one-day win against Lancashire on Saturday with a measured 70 as the Vikings racked up 324-7 to win by 47 runs at Emirates Old Trafford.

He said: "It was a very good win. It was a clinical performance, which is a good thing to start this campaign."

Williamson spent two seasons as Gloucester's overseas player in 2011 and 2012 but the right-hander insisted: "I'll just treat it as another day of cricket.

" It will be nice to catch up with a few old mates – but you often play people you know in the game and it's just another one of those occasions."
