Watch the video here: It happened off the penultimate ball of the 109th over, bowled by Yasir Shah. Fielding at short leg, Azhar faced head first a powerful Matthew Wade pull shot. It hit the top of the helmet even as Ali's evasive action failed to protect his head.

Without the protective gear, it would have been a tragedy. After hitting the helmet, the ball ballooned and was caught by teammate Babar Azam.
