Wagner was only cleared to bowl after completing his warm-ups ahead of play, after an X-ray confirmed he had fractured the fourth toe in his right foot while batting on day two.
He was hit on the foot by Pakistan left-armer Shaheen Shah Afridi and received treatment from Black Caps physio Tommy Simsek at the time, but solidered on and was the last man out, contributing 19 to his side’s total of 431.
As they took the field, Wagner was initially absent, but he returned after sending down a few deliveries and got through three overs before the undisplaced fracture was confirmed overnight.
