Azhar was hit on the tip of his right index finger and is currently under observation of the medical staff, PCB says
Top-order batter Azhar Ali was unable to continue batting Sunday after being hit on the hand by an Ollie Robinson short ball during the fourth day of the Pakistan vs England Test at the Rawalpindi Cricket Stadium.
Initially, after the ball hit him, Azhar received treatment on the field from the physio. However, the batter decided to go back to the pavilion soon after.
