Plays Of The Week
From slam dunks to double tons, these are the most exciting, silly and downright crazy plays in the sport world this week.
The veteran quick bowled only eight overs in New Zealand's second innings after suffering back spasms. The short turnaround between matches meant he was always in extreme doubt to prove his fitness for the second and final Test.
It is expected James Pattinson will return to the XI, after missing last week due to concerns over his ability to play the full match.
Given the comprehensive nature of Australia's win in Wellington, it's unlikely they will make a second change to the attack, although more will be known after the team's main training session in Christchurch on Thursday.
Siddle, who debuted in 2008, has been known for his strong constitution, but has now been injured in three of his last four Tests.
Once a walk-up start, the Victorian has struggled to cement a position since the start of the 2014/15 season, playing six of a possible 16 games due to form and injury issues.
"Peter experienced some discomfort in his back during the first Test in Wellington and has not recovered sufficiently enough to play the Test," Cricket Australia physiotherapist David Beakley said.
"At this stage the plan is for him to stay with the squad in Christchurch for the remainder of the tour before returning to Melbourne for further investigation."
It means Siddle will be able to celebrate with the team should they win or draw the match and return to the top of world cricket.
