Melbourne - Paceman Ryan Harris will return home from the tour of South Africa with a hip injury, Cricket Australia said on Friday.
Harris failed to prove his fitness ahead of Thursday's second Test against the Proteas in Johannesburg.
"Ryan Harris had some right hip pain after the first Test in Cape Town," Australian physiotherapist Alex Kountouris said in a statement.
"He was still experiencing pain bowling during the team training session on Wednesday and was ruled out of the second Test.
"He has had a number of investigations since arriving in Johannesburg that have at this stage excluded serious injury, however he will need to return to Australia for further assessment and to commence his recovery."
Cricket Australia said spinner Michael Beer will also return home.
