Former national selector Merv Hughes expects a fourth pace option to come into Australia's reckoning for the Ashes but not for the day-night Test in Adelaide.
Frontline quicks Mitchell Starc, Josh Hazlewood and Pat Cummins will be put through their paces on Thursday ahead of the pink-ball second Test starting on Saturday.
Hometown quick Chadd Sayers remains in the fold after being 12th man in Brisbane but is likely to again miss out unless one of the first-choice trio pulls up sore.
The Australian camp have been conscious of managing workloads given Cummins' history of ailments and the fact both Starc and Hazlewood have had injury issues in the past 12 months.
But while the search continues for an allrounder to help carry the load, Hughes believes now isn't the time to be resting the quicks.

"Not in the second Test of the series. You pick your best team," Hughes told reporters in Melbourne.
"Pat Cummins is the most intimidating by a long way and he's in your best, so there's no problem picking him.
"When you saw the squad of 13 and the extra two bowlers in the squad, I thought there must have been an injury cloud ... but they got through that and everything's fine."
Coach Darren Lehmann on Tuesday indicated that Mitch Marsh, who has resumed bowling after his shoulder reconstruction, remains a strong candidate for selection.
But Hughes, who took 212 Test wickets for Australia, noted that the quicks did not appear in need of respite.
"The thing about the bowlers is that (only) Hazlewood and Cummins went over to Bangladesh and Hazlewood came home early, so all the bowlers are fresh," Hughes said.
"As the Test series goes on, you think about the one-dayers we've got in January and February and the South Africa tour in March, that's why there's a real liking to have someone in that No.6 spot to bowl and take a little bit of heat off.
"The good thing for the Australian selectors is that they've got options."
