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 theprospect 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.
"At this stage our No 1 priority is getting Jimmy fully healthy and ready for the home summer."
Neesham is expected to bat today if required, as New Zealand strive to save the test.
With concerns of senior seamer Tim Southee's fitness, after he pulled up with an irritated disc in his back on the second morning of the test, it gives added cover.
Another left armer, Neil Wagner, has already been summoned as cover for Southee and will join the squad in Perth.
The 30-year-old McClenaghan has made his impact for New Zealand in the one-day game, where he's taken 76 wickets in 43 ODIs.
"Mitch has the ability to run in all day, bowl quick spells and has experience on the International stage," said Hesson. "He'll bring a lot to the group and is obviously very excited to come and join the squad."
