Steve O'Keefe appears set to play for Australia in the third Test against West Indies, but Peter Siddle will need to prove his fitness.
O'Keefe is likely to be a second spin option for captain Steve Smith as the hosts eye a series sweep in Sydney.
Coach Darren Lehmann confirmed on Wednesday that Australia were likely to play two spinners at the SCG.
"History shows, especially this year the way the wicket has been playing, yes," he told a news conference.
"Weather will come into it, what happens with the game, but the way the wicket has been playing, it's been spinning so there's a real chance we'll do that this time."
On O'Keefe, Lehmann said the left-armer had impressed selectors and was "bowling really well" ahead of the Test starting Sunday.
If he plays, the 31-year-old would be featuring in just his second Test and first since October 2014.
Meanwhile, Lehmann said Siddle would need to prove his fitness after suffering an ankle injury.
But he ruled out resting tireless paceman Josh Hazlewood, who has played in every Test against New Zealand and West Indies.
"If he's fit, he'll play," Lehmann said of Hazlewood.
"Again, we've just got to sum that up. How they pull up, it's a short turnaround as we know, the extra day certainly helps in getting them right for the Sydney Test match.
"But we'll just have to make that call really close to the Sydney Test."
