The New Zealand cricketer Kane Williamson has been undergoing remedial work on his bowling action before he's officially tested for an illegal action.
Williamson was reported by the umpires for a suspect action during New Zealand's second test loss to the West Indies in Trinidad.
Black Caps coach Mike Hesson says Williamson is returning to England to play for county side Yorkshire and will undergo an evaluation on his bowling action at Loughborough University.
Hesson says they're confident that if Williamson's action is ruled to be illegal he can will be able to adjust and he's been working on that during the latter parts of the Carribean tour.
