Tom Blundell has been ruled out of the Black Caps' ODI series against Pakistan with a left-quad strain.
Blundell sustained the injury while batting in the fourth Twenty20 cricket match against Bangladesh and Black Caps physio Nishil Shah explained the injury needed a concentrated period of rehabilitation.
"Tom's been working hard since the injury in Bangladesh," said Shah.
"The injury's not quite where we want it so we think it's best for him to concentrate on his rehab given the big summer of cricket ahead."
Black Caps all-rounder Daryl Mitchell, who was initially joining the side for the T20 series, will now assemble with the ODI squad — becoming available for selection for the second match, once he's completed mandatory isolation.
