Australia batter Steve Smith was ruled out on the morning of the crucial third Ashes Test against England and replaced by Usman Khawaja.<\/b><\/p>\n
Smith missed training on Monday because of illness, then was struck in the groin when he batted in the nets on Tuesday morning.<\/p>\n
The 36-year-old was on the outfield at the Adelaide Oval before play began, only to leave the stadium before the toss took place.<\/p>\n
“Steve has been feeling a little bit unwell over the past couple of days,” said Australia captain Pat Cummins.<\/p>\n
“He gave it a crack this morning, but didn’t think he was going to get up for this one. He’s headed off home.<\/p>\n
“We’re pretty lucky we’ve got someone like Usman who can step right in.”<\/p>\n
Khawaja, who was left out of the Australia XI when it was named on Tuesday, comes in to take Smith’s place at number four.<\/p>\n
Australia, 2-0 up after wins in the first two Tests, will retain the Ashes if they avoid defeat in Adelaide. The hosts won the toss and chose to bat first.<\/p>\n<\/div>\n
