England's captain Ben Stokes is said to be "exhausted" but still "physically able" 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 a quintet of alternative bowlers as the Australian side progressed to 271-4 in their second innings, building a commanding lead of 356 runs at the Adelaide Oval.
The dynamic player had previously spent over five hours at the wicket across two days to compile 83 runs in England's first innings.
During his marathon 198-ball stay, the veteran cricketer was hit on the helmet 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 ground while attempting a stop.
"He could be a little fatigued and just need a bit of time to himself right now," stated Patel.
"From what I understand, he's pretty fit to bowl. I think he's just really exhausted and he's taken a lot out of himself to get through this point in the game."
Given his complicated injury history – 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 significant attention.
Eager to be in the heat of battle, Stokes' decision not to bowl on Friday was curious given it was England's last chance to remain alive in the Ashes series.
At 2-0 down and needing to win in Adelaide to keep their hopes of regaining the urn intact, England had conceded a first-innings deficit of 85 runs.
"My understanding is he operates 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 stayed within the contest by dismissing Australia for around 240 in their second innings and had faint chances at 53-2 and 149-4, only for the hosts to accelerate away through Travis Head's not out 142.
Even though England bowled 66 overs, Stokes chose not to bowl.
"He abstained from bowling but that's probably a different discussion with him," noted ex-New Zealand player Patel.
"I'm not entirely sure. We all know he never performs 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 final day of the tied 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 to its absolute limit, and it was suggested to Patel that the captain felt he might have risked injury if he pushed himself any further in Adelaide.
England are on the verge of another loss in Australia, once again likely to be beaten inside the initial three matches of the series.
If the tourists' loss 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 days of play 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 fifth 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 opportunity for us," said Patel. "It won't be easy, we're going to need something extraordinary. I think it's high time we saw something magical from us."
"Three games in, we've landed some blows but taken a lot. It's about time, now we're backed into a corner, to fight back fiercely."
