The team skipper Ben Stokes is reportedly "worn out" but still "fit and ready" to deliver overs, per assistant coach Jeetan Patel, even though he did not bowl on the third day of a pivotal Ashes Test.
Stokes deployed five other bowlers as the Australian side progressed to 271-4 in their second innings, building a substantial advantage of 356 runs at the Adelaide Oval.
The dynamic player had previously battled for more than five hours at the crease across two days to compile 83 runs in England's initial batting effort.
Throughout his marathon 198-ball stay, the veteran cricketer was hit on the helmet by a fast bowler and suffered bouts of cramp. He also needed a period off the field on the previous day after banging his head on the turf while attempting a stop.
"He could be a bit tired and just require some time to himself right now," commented Patel.
"Based on my knowledge, he's pretty fit to bowl. I think he's just pretty knackered and he's expended a great deal out of himself to get through this point in the match."
Given his chequered injury past – Stokes has not played a full part in any of England's previous four series – any suggestion the Durham man might be carrying a problem draws considerable scrutiny.
Always keen to be in the thick of the action, Stokes' decision not to bowl on Friday was puzzling given it was England's final opportunity to remain alive in the Ashes series.
At 2-0 down and needing to win in Adelaide to keep their hopes of winning back the Ashes intact, England had given up a first-innings deficit of 85 runs.
"All I know 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 probably where he's at."
The tourists could have remained in the contest by dismissing Australia for approximately 240 in their second knock and had slim hopes at 53-2 and 149-4, only for the home team to pull away through Travis Head's not out 142.
Although England bowled 66 overs, Stokes did not use himself.
"He abstained from bowling but that's probably a separate conversation with him," noted 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 most recent occasion Stokes limited his bowling was on the final day of the tied fourth Test against India at Old Trafford in July.
He afterwards was absent for the fifth Test at The Oval with a shoulder injury.
Stokes has a history of pushing his body to its absolute limit, and it was put to Patel that the captain felt he might have endangered himself if he exerted himself any further in Adelaide.
England are on the verge of yet another defeat in Australia, once again likely to be beaten inside the initial three matches of the series.
If the visitors' defeat is completed on Saturday's fourth day, it would mean the destination of the Ashes has been decided in just ten days – the first and second Tests were over in short periods respectively.
Not since 1921, when Australia needed only eight playing days to win in England, has the victor of an Ashes series been decided this quickly.
If a primary objective is to extend this match into a final day, England will also have to pull off the highest successful chase at the Adelaide Oval to keep the series ongoing.
"I still believe there's an opportunity for us," stated Patel. "It won't be easy, we're going to need something extraordinary. I think it's high time we saw something special from us."
"After three matches, we've thrown some but absorbed many. It's about time, now we're with our backs to the wall, to throw some haymakers."
