New Zealand's Kane Williamson banned from bowling by ICC

The cultured number three batsman, who has also proven a useful off-spinner, was subjected to independent analysis after being reported following New Zealand's second Test against West Indies last month.

Tests conducted at Cardiff Metropolitan University revealed the 23-year-old's elbow extension, when bowling, exceeds the 15 degrees of tolerance permitted, leading the International Cricket Council (ICC) to issue a suspension.

Williamson, tipped as a future New Zealand Test captain, will now undergo remedial work on his action, after which he can apply to be re-tested by biomechanical specialists.

"I note the findings of Dr Craig Ranson and his team at Cardiff Met and will concentrate on changing whatever's necessary to return to the bowling crease," Williamson told New Zealand Cricket's website.

"Clearly, the onus is on me to satisfy assessors as to the legality of my action and I'm aware I have some hard work in front of me to achieve that goal.

"It's never nice, going through this sort of process but it will be worth it if I can manage to bowl again at international level."

New Zealand coach Mike Hesson is optimistic Williamson can successfully adjust his action.

"Kane's disappointed, clearly - anyone in his situation would feel the same way," added Hesson.

"He now has a challenge on his hands if he's to bowl again at the top level but we're very hopeful he can manage it."
