The English opening batter Crawley suggested he was not familiar with comments made by skipper Ben Stokes about the dressing room as no place for "those lacking fortitude".
Stokes made this message in several interviews in the wake of his team's loss in the second match of the Ashes versus Australia previously.
In the lead-up to the third Test, where England now face a series loss with a match to spare, Stokes stated he had allowed his sentiment to "drift around" among the squad.
"I've done the necessary discussions in recent days that I required," said the England leader.
However, following the opener made a knock of 85 on the fourth day in the third Test, he stated: "I didn't see that."
"I didn't see and wasn't really looking out for it. We take anything stated in the media with some skepticism," he added.
Raw Conversations and Consistent Messaging
Stokes made the "fragile individuals" comment after England were beaten in the second Test to go two matches behind.
The team afterwards took a holiday to a Queensland resort between the second and third Tests.
Before the Adelaide contest, he revealed his players had held "raw" talks and he had urged them to "display some fight" in their battle to remain alive in the Ashes battle.
Nevertheless, Crawley stated the messaging from Stokes and head coach McCullum had remained consistent with their previous three years in charge.
"It's been extremely upbeat, the same as always," noted the opener. "It's just trying to be optimistic, play our way, with great liberty. We believed we were capable of an extraordinary feat entering this Test."
The Hosts Close of Rapid Series Victory
The opener's wicket on day four came during a crucial triple-strike by Australian spinner Lyon.
Lyon's three wickets in 20 deliveries – he also bowled Brook and Stokes himself – left the chasing side six down for 207 chasing a notional total of 435.
Consequently, the home team require four wickets on Sunday's final day to secure an insurmountable three-nil lead after three matches played.
Defeat will extend England's winless run in this country to 18 consecutive matches and condemn them to a fourth successive away Ashes loss.
The current battle will be completed in just 11 days of play – with England losing the first two Tests in two and four days each.
The last time 1921, when Australia sealed victory in England in eight days, has the destination of the urn been decided so quickly. Australia have also triumphed in 11 days on two other occasions in the 21st century.
"This is disappointing," said the batsman. "We came here to regain the Ashes and we're facing elimination at this point."
"There will still be significant pride at stake and we'll definitely view it with that mindset," Crawley added.
"The challenge has been difficult. They're a formidable team. It was always going to be hard touring here to face them. They were the favourites and have demonstrated their quality."
Ollie Pope's Position In Question
Although Crawley's innings in the third Test likely secures doubts about his short-term future in the side, Ollie Pope appears under immense pressure for his spot in the Melbourne Test on Boxing Day.
The Surrey batsman was out for 17 in England's second knock on day four, adding to his poor record versus Australia.
In 16 Ashes innings, Pope has never made a half-century and averages 17.62.
A solitary other English batsman in over a century – Amiss – has featured an equal number of innings in the top order in the Ashes and recorded a lower average.
But, the opener said any notion his teammate is being scrutinised comes from "the media" – meaning the journalists – "not inside the camp."
"The squad is fully aware of his considerable talent," added Crawley. "Ollie has enjoyed a good year to be frank."
"He has produced some really good knocks. It is talk externally. There is no discussion of that nature on Ollie in the camp," he concluded.
