Matthew Wade's Test career hangs in the balance, with Peter Handscomb donning the wicketkeeping gloves at training ahead of the second Test against Bangladesh in Chittagong.
Australia's XI for the second Test starting on Monday remains a mystery, with Usman Khawaja also facing a nervous wait to learn whether he will retain his No.3 spot.
With Australia staring down the barrel of an embarrassing 2-0 series defeat to the ninth-ranked Bangladesh, Handscomb is every chance to take over from Wade as wicketkeeper.
Handscomb donned the gloves for about 20 minutes at training on Sunday, which skipper Steve Smith had earlier declared would be enough preparation should selectors choose to go down that path.
Wade did not attend the optional session but kept wicket throughout Australia's main practice on Saturday while Handscomb fielded at short leg.
Smith confirmed the XI would not be named until the toss after heavy rain denied him the chance to take a fresh look at the pitch.
"We're not sure which way we're going to go there," Smith said of the wicketkeeping decision.
"It's going to depend on the wicket and what we think the best make-up of the side is. It's certainly good to have Pete here as an option if we want to go down that path."
Left-arm spinner Steve O'Keefe appears most likely to replace the injured Josh Hazlewood ahead of back-up paceman Jackson Bird.
Australia rarely play three spinners but the option is in play after Bangladesh spun their way to success in Dhaka.
If either Wade or Khawaja is dumped, Hilton Cartwright could come into the side to provide another batting option and support Pat Cummins with his medium pace.
Wade has averaged just 21 with the bat since being recalled last summer.
The fact that selectors are giving serious thought to playing a part-time wicketkeeper suggests the 29-year-old's career is on the rocks ahead of the summer Ashes series.
Test greats Ian Healy and Mark Taylor have both cautioned against the move, with Healy suggesting it could compromise Handscomb's batting.
But Smith's confirmation that Handscomb will take the gloves for Victoria in the domestic one-day competition indicates he is considered a viable wicketkeeper at international level.
With more than a third of the nation under water as a result of devastating monsoon flooding, Chittagong experienced heavy rain throughout the weekend with more predicted during the Test.
A washout would either prevent Australia from squaring the ledger or spare them the indignity of a series defeat that would send them tumbling to No.6 in the world Test rankings.
