England all-rounder Ben Stokes bowled only two overs on the first day of the second Test against New Zealand because of a knee injury.
England said the 28-year-old "has some pain in his left knee" and "felt some discomfort at the end of his second over".
Stokes will be assessed on whether he can bowl again in the game.
New Zealand, who lead 1-0 in the two-Test series, were 173-3 when rain brought an early close in Hamilton.
He took 2-74 in England's innings defeat in the first Test in Mount Maunganui but bowled the fewest overs of England's four seamers.
