The team skipper Ben Stokes is said to be "exhausted" but still "physically able" to deliver overs, according to team coach Jeetan Patel, even though he abstained from bowling on the third day of a critical Ashes Test.
Stokes utilized five other bowlers as the Australian side progressed to 271-4 in their second innings, establishing a substantial advantage of 356 runs at the venue.
The dynamic player had earlier spent over five hours at the crease across two days to compile 83 runs in England's initial batting effort.
During his extended 198-ball stay, the 34-year-old was struck on the head by Mitchell Starc and suffered bouts of cramp. He also needed a period off the field on Friday after banging his head on the turf while trying to field the ball.
"He might be a little fatigued and just need a bit of time to himself right now," stated Patel.
"From what I understand, he's quite ready to bowl. I think he's just really exhausted and he's taken a lot out of himself to reach this point in the match."
Given his chequered injury past – Stokes has not played a full part in any of England's last four series – any suggestion the Durham man might be carrying a problem attracts considerable scrutiny.
Always keen to be in the heat of battle, Stokes' absence from the attack on Friday was puzzling given it was England's final opportunity to remain alive in the Ashes series.
At 2-0 down and requiring a victory in Adelaide to keep their hopes of regaining the urn intact, England had given up a first-innings deficit of 85 runs.
"My understanding is he goes at 100%," said Patel. "If he thinks he can't do it at 100%, I don't think he's going to do it. That's probably where he's at."
The tourists could have remained in the match by bowling out Australia for around 240 in their second knock and had faint chances at 53-2 and 149-4, only for the hosts to pull away through Travis Head's unbeaten 142.
Although England delivered 66 overs, Stokes chose not to bowl.
"He abstained from bowling but that's probably a different discussion with him," noted former New Zealand international Patel.
"I don't actually know. We all know he never performs at 80%. Maybe he thought he was a risk, so he didn't bowl."
The last time Stokes limited his bowling was on the last day of the drawn fourth Test against India at Old Trafford in July.
He afterwards was absent for the fifth Test at The Oval with a shoulder problem.
Stokes has a reputation of pushing his body past breaking point, and it was suggested to Patel that the captain felt he might have risked injury if he exerted himself any further in Adelaide.
England are on the verge of another loss in Australia, once again likely to be beaten inside the first three Tests of the series.
If the visitors' defeat is sealed on Saturday's fourth day, it would mean the destination of the Ashes has been determined in just ten days – the opening two matches were over in two and four days respectively.
Not since 1921, when Australia needed only eight playing days to win in England, has the winner of an Ashes series been determined so swiftly.
If a first goal is to extend this match into a fifth day, England will also have to pull off the greatest run-chase at the Adelaide Oval to keep the series ongoing.
"I remain convinced there's an opportunity for us," said Patel. "It will be difficult, we're going to need something magical. I think it's high time we saw something magical from us."
"After three matches, we've landed some blows but absorbed many. It's about time, now we're backed into a corner, to throw some haymakers."
