Steve Smith has cast a shadow over Australia's push for victory in the first Test against South Africa in Durban after he was struck heavily on the helmet by a bouncer from Anrich Nortje on the morning of day four. Smith was undergoing further assessment for a potential concussion and spent the final session watching from the team viewing area in his tracksuit. He was never expected to take the field on the fourth evening and is likely to miss day five.
The delivery drew winces from the small gathering of spectators at Kingsmead, with Smith taking his eyes off the rapid delivery and ducking an instant before the ball clanged off the side of his helmeted head.
His absence would be a significant blow for Australia, who are led by Josh Hazlewood and skipper Pat Cummins, with Matt Renshaw claiming his first Test wicket. The team is closing in on a meritorious victory, but must now wait to discover whether Smith will be out of the next Test or even the series if a delayed concussion is confirmed.
