Peter Siddle misses out on training ahead of Sydney Test
Siddle, 31, suffered an ankle injury during the recently concluded Boxing Day Test against West Indies in Melbourne, which Australia went on to win by 177 runs.
The Victorian fast bowler failed to train with the squad on Friday which increases the probability of Australia playing two spinners - Stephen O' Keefe and Nathan Lyon in the final game of the series.
After a seven-wicket haul in the first game, Josh Hazlewood went wicketless in the second Test raising concerns about his heavy workload.
However Hazlewood is expected to feature in the final Test incase Siddle fails to prove his fitness ahead of the game.
Australian head coach Darren Lehmann said that the bowling performance of Mitchell Marsh in the Melbourne Test is an encouraging sign which can allow Australia to play two spinners especially in spin-friendly conditions.
"It (Marsh’s bowling development) allows us to really still play three genuine quicks and … two spinners," said Lehmann.
"That’s a real option for us where we’re going to, maybe not so much New Zealand (where Australia plays two Tests in February) but looking further ahead to subcontinent conditions where we need to make sure we’ve got two spinners up and running."
Having already won the Frank Worrell Trophy, Australia will lock horns with West Indies in the final game of the series in Sydney on 3rd January.
