Pakistan beat New Zealand by six wickets in the second day-night international in Abu Dhabi on Friday but the match was overshadowed by a worrying injury to opening batsman Imam-ul-Haq who was taken to hospital after being hit on the head by a short ball.

Imam, on 16, was forced to retire after a short delivery from fast bowler Lockie Ferguson hit the grill of his helmet, making him dizzy before he fell to the ground.
