Allrounder Jimmy Neesham has been ruled out of the rest of New Zealand's tour of Australia.
Neesham looked uncomfortable bowling in both innings of the first test, and coach Mike Hesson said Neesham had experienced back pain.
His replacement will be Auckland fast bowler Mitchell McClenaghan, and that offers the prospect of a test debut for the burly left armer at either Perth in the second test starting on Friday or in the third international in Adelaide from November 27.
''Jimmy has worked hard to get back to fitness following his injury earlier this year, but at this stage still experiences discomfort when bowling extended loads," said Hesson.
"Jimmy will return to New Zealand for further medical assessment and we'll continue to monitor his situation.
