England's captain Ben Stokes is said to be "worn out" but still "fit and ready" to deliver overs, according to team coach Jeetan Patel, despite he abstained from bowling on the day three of a critical Ashes Test.
Stokes deployed five other bowlers as the Australian side progressed to 271-4 in their follow-on, establishing a substantial advantage of 356 runs at the venue.
The versatile all-rounder had earlier spent over five hours at the wicket across two days to compile 83 runs in England's first innings.
Throughout his extended 198-ball stay, the veteran cricketer was struck on the head by Mitchell Starc and experienced 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," commented Patel.
"From what I understand, he's quite ready to bowl. I think he's just really exhausted and he's expended a great deal out of himself to get through this point in the match."
Considering his complicated injury history – Stokes has not played a full part in any of England's last four series – any indication the Durham man might be carrying a problem attracts significant attention.
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 remain alive in the Ashes series.
At trailing 2-0 and requiring a victory in Adelaide to keep their aspirations of winning back the Ashes 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 slim hopes 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 didn't bowl but that's perhaps a different discussion with him," said ex-New Zealand player Patel.
"I don't actually know. We all know he never performs at 80%. Maybe he thought he was a liability, so he didn't bowl."
The most recent occasion 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 injury.
Stokes has a history of pushing his body past breaking point, and it was put 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 yet another defeat in Australia, once again likely to be beaten inside the initial three matches of the series.
If the tourists' loss is completed on Saturday's fourth day, it would mean the outcome of the Ashes has been determined in just ten days – the opening two matches 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 determined so swiftly.
If a first goal is to prolong the game into a final day, England will also have to achieve the greatest run-chase at the Adelaide Oval to keep the series ongoing.
"I still believe there's an chance for us," stated Patel. "It will be difficult, we're going to need something extraordinary. I think it's about time we witnessed something special from us."
"After three matches, we've landed some blows but taken a lot. It's time, now we're backed into a corner, to fight back fiercely."
