New Zealand's woes in the ongoing Australia tour have aggravated with the latest injury blow to bowling spearhead Trent Boult.
The left-arm speedster fractured his non-bowling hand while batting on Saturday and will be unavailable for the third Test in Sydney.
Boult, whose troubles with a side strain kept him out of the first Test of the series, copped a blow on the gloves from a Mitchell Starc bouncer on day three.
He initially required medical attention but bowled in Australia's second innings in the afternoon.
He was then taken to the hospital during the tea break where an X-ray confirmed a fracture, ruling him out for four weeks.
"Trent Boult will return home to New Zealand following the 2nd Test after suffering a fracture to the second-metacarpal of his right hand while batting on day three," the statement released from New Zealand Cricket read.
"He will require around four weeks of rehabilitation. A replacement player will be confirmed in due course."
Boult had a bright start to the Boxing Day Test, snaring Joe Burns in the first over of the match - his sole wicket in Australia's first innings.
His absence is a significant setback to New Zealand, who are struggling to keep the series alive against Australia in Perth.
"Obviously gutting news for Trent and for our group to have someone like that ruled out with his injury. Disappointing," opening batter Tom Latham said, reflecting on the unfortunate development.
