BLACKCAPS fast bowler Trent Boult has been ruled out of the second ANZ Test against Pakistan beginning tomorrow, after feeling discomfort in his right knee during training yesterday.

Boult has some irritation in the joint of his right knee, which has been managed in recent weeks.

BLACKCAPS Coach Mike Hesson said: 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.

Doug Bracewell has joined the squad in Hamilton.
