New Zealand opener Will Young drove Shaheen Afridi through the covers to beat the infield, with Zaman setting off in pursuit. He cut it off before palming it over to Babar Azam to throw it back to the keeper, but immediately appeared to feel discomfort in his lower back. He signalled that he needed to be replaced, and went off the field with the physio, though he walked unaided back to the dressing room.

"Fakhar Zaman is being assessed and examined for a muscular sprain and further updates will be provided in due course," the PCB said in a statement.

Pakistan had been hampered by an injury to Saim Ayub in similar circumstances, one that ultimately kept him out of the Champions Trophy. In a Test against South Africa, he set off in pursuit of a ball to the boundary and ended up twisting his ankle. It resulted in a fracture that will keep him out until at least the middle of March. Fakhar, who until then wasn't part of Pakistan's ODI plans, came back into the side as Ayub's replacement, and made an impressive return, scoring 84 off 69 and 41 off 28 in his first two matches back in the side.

The game marks the return of ICC tournament cricket to Pakistan after 1996, with huge crowds building up outside the National Stadium in Karachi in the hours before the start. The opening ceremony was attended by Pakistan's president Asif Ali Zardari and had an air force fly-past parade after the toss, which Pakistan won and asked New Zealand to bat.
