England opener Crawley has indicated he had no knowledge of comments from captain Ben Stokes regarding the dressing room as no place for "weak men".
The all-rounder delivered this message in several interviews following England's loss in the second Ashes against Australia previously.
In the lead-up to the third Test, where England are staring at defeat with a match to spare, the captain stated he had let his message to "drift around" among the squad.
"I have completed the necessary discussions in recent days that I required," said Stokes.
But, following Crawley made 85 on the fourth day in Adelaide, he stated: "I missed those remarks."
"I wasn't actively searching for it. We take everything that is said in the press with a pinch of salt," Crawley continued.
Frank Discussions and Consistent Messaging
Stokes made the "weak men" comment after his side were beaten in the second Test to go 2-0 down.
The England squad subsequently took a holiday to a Queensland resort in the gap between the second and the upcoming Tests.
Before the Adelaide contest, Stokes 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, the Kent batsman asserted the messaging from Stokes and coach McCullum had remained consistent with their previous three years in charge.
"It's been extremely upbeat, the same as always," said the opener. "It's just trying to be optimistic, playing our brand, with lots of freedom. It felt like we could do something special going into this game."
Australia On the Verge of Rapid Series Victory
The opener's wicket on day four was part of a decisive triple-strike by Australia off-spinner Nathan Lyon.
The spinner's three wickets in a short spell – he also bowled Brook and Stokes himself – left the chasing side six down for 207 chasing a daunting total of 435 runs.
Consequently, the home team require four wickets on the final day to secure an insurmountable 3-0 advantage after three Tests.
Defeat would prolong England's winless run in this country to 18 consecutive matches and ensure a fourth successive overseas Ashes loss.
This series will be completed in only eleven days of cricket – after England fell the first two Tests in rapid time each.
Not since 1921, when Australia completed victory in England in eight days, has the destination of the Ashes urn been determined more swiftly. The hosts have also won in eleven days on two other occasions in the modern era.
"It's disheartening," said Crawley. "We came here to win the Ashes and we're staring down the barrel at this point."
"There remains significant pride at stake and we'll definitely view it like that," he continued.
"The challenge has been tough. They're a formidable side. It was inevitably tough coming here against them. They entered as the favourites and have demonstrated their quality."
Pope's Place Under Scrutiny
Although the opener's performance in the third Test probably answers questions about his short-term future in the side, Ollie Pope looks under immense pressure for his spot in the Melbourne Test on Boxing Day.
Pope was out for 17 in the team's second innings on Saturday, extending his modest returns against the old enemy.
In sixteen Ashes knocks, the Surrey man has never made a half-century and boasts an average of 17.62.
Only one other English batsman in over a century – Dennis Amiss – has played an equal number of innings in the top six in Ashes Tests and recorded a poorer average.
But, the opener insisted any notion his teammate is under the microscope originates with "you guys" – meaning the journalists – "and not within the team."
"The squad is fully aware how good of a player he is," added he. "He has had a productive year to be frank."
"He has played several excellent innings. It is noise externally. There's no discussion like that on Ollie amongst the players," Crawley finished.
