England's captain Ben Stokes is said to be "worn out" but still "physically able" to bowl, per assistant coach Jeetan Patel, even though he abstained from bowling on the third day of a pivotal Ashes Test.
Stokes utilized five other bowlers as Australia moved to 271-4 in their follow-on, building a commanding lead of 356 runs at the venue.
The dynamic player had previously spent over five hours at the crease over two days to compile 83 runs in England's first innings.
During his marathon 198-ball stay, the 34-year-old was hit on the helmet by a fast bowler and experienced bouts of cramp. He also needed a period off the field on Friday after hitting his head on the ground 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 really exhausted and he's expended a great deal out of himself to reach this point in the game."
Considering his complicated injury history – Stokes has not played a full part in any of England's previous four series – any indication the Durham man might be nursing an issue 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 aspirations of regaining the urn intact, England had conceded a first-innings lead 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 visiting side could have remained in the contest by bowling out 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.
Even though England bowled 66 overs, Stokes did not use himself.
"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 risk, so he didn't bowl."
The most recent occasion Stokes limited his 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 history of driving himself past breaking point, and it was suggested 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 another loss in Australia, once again likely to be beaten inside the initial three matches of the series.
If the visitors' defeat is completed on day four, it would mean the outcome of the Ashes has been decided 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 victor of an Ashes series been determined so swiftly.
If a first goal is to extend this match 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 about time we saw something magical from us."
"Three games in, we've thrown some but absorbed many. It's time, now we're with our backs to the wall, to throw some haymakers."
