The team skipper Ben Stokes is said to be "exhausted" but still "fit and ready" to deliver overs, according to assistant coach Jeetan Patel, despite he abstained from bowling on the day three of a critical Ashes Test.
Stokes deployed a quintet of alternative bowlers as Australia moved to 271-4 in their second innings, establishing a substantial advantage of 356 runs at the Adelaide Oval.
The dynamic player had earlier battled for more than five hours at the crease across two days to score 83 runs in England's initial batting effort.
Throughout his marathon 198-ball stay, the 34-year-old was struck on the head by Mitchell Starc and experienced muscle cramps. He also needed a period off the field on the previous day after banging his head on the turf while attempting a stop.
"He might be a little fatigued and just need a bit of time to himself right now," stated Patel.
"Based on my knowledge, 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 game."
Considering his complicated injury past – Stokes has not been fully available in any of England's last four series – any suggestion the Durham man might be nursing an issue attracts significant attention.
Eager to be in the thick of the action, Stokes' absence from the attack on Friday was curious given it was England's last chance to stay in the Ashes series.
At trailing 2-0 and requiring a victory in Adelaide to keep their hopes of winning back the Ashes intact, England had conceded a first-innings lead of 85 runs.
"My understanding is he goes at 100%," remarked Patel. "If he thinks he can't do it at 100%, I don't think he's going to do it. That's likely where he's at."
The visiting side could have remained in the match by dismissing Australia for around 240 in their second knock and had slim hopes at 53-2 and 149-4, only for the hosts to accelerate away through Travis Head's not out 142.
Although England bowled 66 overs, Stokes chose not to bowl.
"He didn't bowl but that's perhaps a separate conversation with him," said ex-New Zealand player Patel.
"I'm not entirely sure. We all know he doesn't do anything at 80%. Maybe he thought he was a risk, so he didn't bowl."
The last time Stokes curtailed his own bowling was on the last day of the drawn fourth Test against India at Old Trafford in July.
He afterwards missed the fifth Test at The Oval with a shoulder problem.
Stokes has a history of pushing his body past breaking point, and it was put to Patel that the captain felt he might have endangered himself if he pushed himself any further in Adelaide.
England stand on the edge of yet another defeat in Australia, once again likely to be beaten inside the first three Tests of the series.
If the visitors' defeat is sealed on day four, it would mean the destination of the Ashes has been determined in 10 days – the first and second Tests 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 decided this quickly.
If a primary objective is to prolong the game into a final day, England will also have to achieve the highest successful chase at the Adelaide Oval to keep the series alive.
"I remain convinced there's an chance for us," stated Patel. "It will be difficult, we're going to need something extraordinary. I think it's high time we witnessed something magical from us."
"After three matches, we've thrown some but taken a lot. It's about time, now we're with our backs to the wall, to fight back fiercely."
