Australia suffered a shocking pre-match setback on the opening morning of the third Ashes Test at the Adelaide Oval on Wednesday, with Steven Smith ruled out of the match in extraordinary circumstances just moments before the start of play. Cricket Australia confirmed that Smith was withdrawn after experiencing vertigo-type symptoms.

Smith has battled this issue intermittently in the past. The decision was taken on medical advice following a tense warm-up period that saw the former captain bat in the nets before ultimately leaving the ground.

The late withdrawal opened the door for Usman Khawaja, who earned a surprise recall to the XI just a day after it appeared unlikely he would play another Test for Australia.

"Over the past few days he has been feeling unwell, with symptoms including nausea and dizziness," CA stated in a statement.

"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."

Smith missed training on Monday due to illness; however, he batted at the optional session on Tuesday.
