England's captain Ben Stokes is said to be "worn out" but still "fit and ready" to bowl, per assistant coach Jeetan Patel, even though he did not bowl on the third day of a pivotal Ashes Test.
Stokes utilized a quintet of alternative bowlers as the Australian side moved to 271-4 in their second innings, building a commanding lead of 356 runs at the venue.
The dynamic player had earlier spent over five hours at the crease over two days to score 83 runs in England's initial batting effort.
During his extended 198-ball stay, the veteran cricketer was hit on the helmet by a fast bowler and suffered bouts of cramp. He also required time off the field on Friday after banging his head on the ground while trying to field the ball.
"He could be a bit tired and just need a bit of time to himself right now," stated 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 reach this point in the game."
Given his chequered injury history – Stokes has not played a full part in any of England's last four series – any indication the star all-rounder might be carrying a problem draws considerable scrutiny.
Always keen to be in the heat of battle, Stokes' decision not to bowl on Friday was puzzling given it was England's final opportunity to stay in the Ashes series.
At trailing 2-0 and needing to win in Adelaide to keep their aspirations of regaining the urn alive, England had conceded a first-innings lead of 85 runs.
"My understanding is he operates 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 visiting side could have stayed within the contest by dismissing 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.
Even though 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 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 last 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 reputation of driving himself past breaking point, 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 first three Tests of the series.
If the tourists' loss is completed 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 victor of an Ashes series been determined so swiftly.
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 ongoing.
"I still believe there's an opportunity for us," said Patel. "It won't be easy, we're going to need something extraordinary. I think it's about time we witnessed something magical from us."
"After three matches, we've landed some blows but taken a lot. It's about time, now we're backed into a corner, to fight back fiercely."
