Should he be ruled out with concussion, attention will quickly turn to who replaces Smith in the Australian XI for the second Test.
“I hope he’s OK,” Beau Webster said of Smith at the end of day four.
“He obviously copped a nasty knock in the head there. Hopefully he’s back out with this either tomorrow or in the next Test.”
Josh Inglis fractured his finger in a white-ball series recently but is back training with the Test group and could be a replacement option, while Cam Green could be available in time for the next match after missing Durban due to injury.

“The boys look like they’re tracking well,” Webster said.
“Ingles got back to us from Perth in the last couple of days. He’s had a hit today.
“Greenie looks like he’s up and he’s running. I haven’t really spoken to him. I’ve got no real time timeline there. I’m not a physio or a doctor, so I’ve got no idea.”
Sam Harper and Cooper Connolly are also in the squad.
