New Zealand’s fourth-highest Test wicket-taker with 255 scalps, Boult shapes as the most likely bowler to threaten Australia’s batsmen, particularly in the day-night Test at Optus Stadium.
In his two Tests with a pink ball, Boult has claimed 16 wickets at under 13 runs apiece, including seven wickets against the Australians in Adelaide four years ago when he ripped through the second-innings top order.
De Grandhomme has a tear to his left lower abdominal muscle, sustained while fielding late in the Test at Bay Oval.
The 33-year-old has emerged as an integral part of New Zealand’s make-up, averaging 40.33 with the bat and 29.63 with his medium pace, the sort of figures that compare favourably with any of the world’s current all-rounders.
Speedster Lockie Ferguson is favoured to make his Test debut as Boult’s replacement.
Like Ferguson, Mitchell has represented New Zealand in white-ball cricket but not Tests.
The son of former All Blacks rugby coach John Mitchell, he could make a maiden Test appearance on his home ground of Seddon Park as a like-for-like replacement for de Grandhomme.
