England's captain Ben Stokes is said to be "exhausted" but still "fit and ready" to deliver overs, per team coach Jeetan Patel, even though he abstained from bowling on the third day of a pivotal Ashes Test.
Stokes utilized a quintet of alternative bowlers as Australia progressed to 271-4 in their second innings, building a substantial advantage of 356 runs at the venue.
The versatile all-rounder had previously spent over five hours at the wicket over two days to compile 83 runs in England's initial batting effort.
Throughout his marathon 198-ball stay, the 34-year-old was struck on the head 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 little fatigued and just need a bit of time to himself right now," stated Patel.
"From what I understand, he's quite ready 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 game."
Considering his chequered injury history – Stokes has not played a full part in any of England's last four series – any indication the Durham man might be nursing an issue draws significant attention.
Always keen to be in the heat of battle, Stokes' absence from the attack on Friday was curious 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 intact, England had conceded a first-innings deficit of 85 runs.
"All I know is he goes 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 likely where he's at."
The tourists could have remained in the match by bowling out Australia for approximately 240 in their second knock and had faint chances at certain scorelines, only for the home team to pull away through Travis Head's not out 142.
Even though England delivered 66 overs, Stokes chose not to bowl.
"He didn't bowl but that's probably a different discussion with him," noted former New Zealand international Patel.
"I'm not entirely sure. We all know he doesn't do anything at 80%. Maybe he thought he was a liability, so he didn't bowl."
The last time Stokes limited his bowling was on the final day of the drawn fourth Test against India at Old Trafford in July.
He subsequently missed the fifth Test at The Oval with a shoulder problem.
Stokes has a history of driving himself to its absolute limit, 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 probably facing defeat inside the first three Tests of the series.
If the tourists' loss is completed on day four, it would mean the destination of the Ashes has been determined in just ten 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 decided this quickly.
If a primary objective is to prolong the game into a final day, England will also have to pull off the greatest run-chase at the Adelaide Oval to keep the series ongoing.
"I remain convinced there's an opportunity for us," stated Patel. "It won't be easy, we're going to need something magical. I think it's about 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."
