According to The Times of India, Smith was hit by a delivery while Australia batted in the second innings and subsequently underwent concussion screening, which he passed. Cricinfo noted that as of Monday afternoon he had not been diagnosed with concussion, indicating the assessment was still ongoing.
The Australian side brought Smith back onto the field on the final day after South Africa’s chase of 319 runs had stalled at two wickets by lunch. He contributed a catch to dismiss Kyle Verreynne, bolstering Australia’s chances, as the second Test of the series is scheduled to start on Sunday.
