Shan Masood, a Pakistan batsman, was taken to the hospital for scans on Friday after being hit on the head during a practise session prior to the team’s first match at the Twenty20 World Cup in Australia.
On Sunday, Pakistan will kick off their campaign against archrival India in Melbourne.
Masood, 33, is regarded as a technically sound top-order batsman who has two half-centuries for Pakistan in 12 T20s since making his debut in September.
Social media images showed Pakistan players and team staff encircling Masood, with a distraught Nawaz sitting on his knees.
Pakistan defeated India in the T20 World Cup semi-finals last year, led by Babar Azam.
