Skipper Michael Clarke alarmed Australian ranks on Monday when he appeared to turn his ankle before completing a net session without complaint just days before the start of the second Ashes Test.
Clarke was seen limping slightly, favouring his right ankle, as the Australians performed fielding drills at Adelaide Oval in preparation for the match against England starting on Thursday.
He repeatedly flexed his ankle but then headed for some batting practice and appeared unaffected throughout.
"He has since completed a nets session and is OK," Cricket Australia tweeted.
Clarke scored a century in the first Test in Brisbane and is a crucial player for Australia as they seek to reverse the 3-0 series loss to England earlier this year.
The captain was initially in doubt for Brisbane with a long-standing back problem, but recovered in time.
