New Zealand fast bowler Trent Boult has been ruled out of the second test against Pakistan with a knee injury.
The 27-year-old aggravated a problem with the joint in his right knee in training and will be forced to sit out the encounter in Hamilton.
Coach Mike Hesson confirmed: "Trent has had a minor discomfort in his knee dating back to the tour of India, which we've been managing in recent weeks.
"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."
Boult, who has played in 44 consecutive Tests since 2012, has been replaced in the squad by Doug Bracewell.
New Zealand claimed the first Test by eight wickets, in which Boult took 5 for 76.
