England's captain Ben Stokes is reportedly "exhausted" but still "fit and ready" to bowl, according to team coach Jeetan Patel, despite he did not bowl on the day three of a critical Ashes Test.
Stokes deployed five other bowlers as the Australian side moved to 271-4 in their second innings, establishing a substantial advantage of 356 runs at the Adelaide Oval.
The versatile all-rounder had previously battled for more than five hours at the wicket over two days to score 83 runs in England's first innings.
Throughout his marathon 198-ball innings, the veteran cricketer was struck on the head by Mitchell Starc and suffered bouts of cramp. He also required time off the field on the previous day after banging his head on the ground while attempting a stop.
"He might be a little fatigued 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 pretty knackered and he's taken a lot out of himself to get through this point in the game."
Given his chequered injury history – Stokes has not been fully available in any of England's last four series – any indication the Durham man might be carrying a problem attracts considerable scrutiny.
Eager to be in the heat of battle, Stokes' absence from the attack on Friday was puzzling given it was England's last chance to remain alive in the Ashes series.
At trailing 2-0 and needing to win in Adelaide to keep their hopes of winning back the Ashes intact, England had conceded a first-innings deficit of 85 runs.
"All I know 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 likely where he's at."
The visiting side could have remained in the match by bowling out Australia for around 240 in their second innings and had slim hopes at certain scorelines, only for the home team to pull 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 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 limited his bowling was on the last day of the drawn 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 pushing his body to its absolute limit, and it was suggested to Patel that the captain felt he might have endangered himself if he pushed himself any further in Adelaide.
England are on the verge of yet another defeat in Australia, once again probably facing defeat inside the initial three matches of the series.
If the visitors' defeat 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 short periods respectively.
Not since 1921, when Australia needed only eight days of play to win in England, has the winner of an Ashes series been determined so swiftly.
If a primary objective is to extend this match into a fifth day, England will also have to pull off the highest successful chase at the Adelaide Oval to keep the series alive.
"I remain convinced there's an opportunity for us," stated Patel. "It will be difficult, we're going to need something magical. 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 time, now we're backed into a corner, to fight back fiercely."
