Rotorua's Black Caps fast bowler Trent Boult has been ruled out of the second test against Pakistan, after feeling discomfort in his right knee during training on Wednesday.
Boult has some irritation in the joint of his right knee, which has been managed in recent weeks.
"Trent has had a minor discomfort in his knee dating back to the tour of India, which we've been managing in recent weeks," Black Caps coach Mike Hesson said.
"Unfortunately he irritated it further while fielding in the first test. He bowled again and we were optimistic he would be ready for Hamilton, but during training on Wednesday felt further pain and has subsequently been ruled out of the test."
"We're hopeful at this stage that he'll be available for the Chappell-Hadlee series in Australia, but will continue to monitor him over the coming days," Hesson said.
