Trent Boult has been ruled out for the remainder of the one-day international series against England due to stress on his back. He is being sent home as a precaution tomorrow.
No replacement has been added to the squad.
The 25-year-old suffered discomfort after the second match which New Zealand won by 13 runs via Duckworth-Lewis Method to level the series 1-1.
Scans are yet to confirm a diagnosis.
Before the third match overnight, Boult had been New Zealand's best bowler in the series, taking six wickets at 18 and conceding 5.4 runs per over. No teammate had taken as many wickets or gone for less than a run a ball.
