New Zealand skipper and batting mainstay Kane Williamson is doubtful while spinner Mitchell Santner has been ruled out of the second Test against England that begins at Edgbaston here on Thursday. The injuries to two key players come 10 days before New Zealand's World Test Championship final against India gets underway at Southampton.

While Santner is out after a cut in his finger opened up during last week's first Test at Lord's and led to bleeding, Williamson has a niggle in his elbow.
