Smith misses out of Adelaide Test with vertigo-like symptoms

Steven Smith was ruled out of the third Ashes Test on the morning of the match after experiencing vertigo-like symptoms, triggering a late reshuffle in Australia's XI and opening the door for Usman Khawaja's recall.

Cricket Australia confirmed shortly before the start of play that Smith was dealing with dizziness and nausea, symptoms he has battled intermittently in the past. The batter had a fitness test on the morning of the Adelaide Test before being ruled out, and he left the ground.

"Over the past few days he has been feeling unwell, with symptoms including nausea and dizziness," a Cricket Australia spokesperson said. "He was assessed and monitored closely and was close to being available to play. However, given the persistence of symptoms, a decision was made not to proceed.

"He is being treated for a potential vestibular issue. This is something Steve has experienced intermittently in the past and is being managed accordingly. He is expected to be available for the Boxing Day Test in Melbourne."

Smith had missed training on Monday but returned to the nets on the following day. He did not appear at his best during the session and was also struck in the groin, which forced him to take an extended break.

Pat Cummins, returning to lead the side after missing the first two Tests, confirmed Smith's withdrawal after winning the toss and said Khawaja would replace him at No. 4.

"Steve's been feeling a bit unwell the last couple of days," Cummins said. "He came and gave it a crack this morning but didn't think he was going to get up for this one. So he's headed off home. Pretty lucky we've got someone like Usman who can step right in. Usman will bat at No. 4."
