The English opening batter Crawley suggested he was not familiar with comments from captain Ben Stokes about the dressing room not being "those lacking fortitude".
Stokes made those words in several interviews following England's defeat in the second Ashes series against the Australians previously.
In the lead-up to the Adelaide Test, where the visitors now face a series loss at the earliest opportunity, Stokes stated he had allowed his message to "drift around" within the playing group.
"I have completed all the talking in recent days that I required," said Stokes.
However, after Crawley scored a knock of 85 on the penultimate day in the third Test, he commented: "I didn't see that."
"I wasn't actively searching for it. Our approach is to take anything stated in the press with a pinch of salt," he added.
Raw Conversations and Consistent Messaging
The captain issued his "weak men" comment after England suffered a loss in the second Test to fall 2-0 down.
The team subsequently went on a break to a Queensland resort between the second and the upcoming matches.
Prior to the Adelaide contest, he said his team had held "honest" talks and he had asked them to "display some fight" in their battle to remain alive in the Ashes battle.
Nevertheless, Crawley asserted the guidance from Stokes and head coach McCullum had remained consistent with their previous three years in charge.
"The atmosphere has been extremely upbeat, the same as always," noted Crawley. "The focus is on maintaining positivity, play our way, with lots of freedom. We believed we could do something special entering this game."
Australia On the Verge of Rapid Series Victory
Crawley's dismissal late on Saturday came during a crucial three-wicket burst by Australia spinner Lyon.
Lyon's three wickets in a short spell – he also bowled Brook and Ben Stokes – left England six down for 207 in pursuit of a daunting target of 435 runs.
This means, Australia require just four more wickets on Sunday's final day to move to an unassailable 3-0 advantage after three Tests.
A loss would prolong the English team's drought in this country to 18 Tests and ensure a fourth successive away Ashes loss.
This series will be completed in just eleven days of play – with England fell the initial matches in rapid time respectively.
Not since 1921, when the Australians completed victory in the UK in eight days, has the destination of the urn been decided so quickly. The hosts have also triumphed in eleven days on two other occasions in the modern era.
"This is disheartening," said Crawley. "We came here to regain the Ashes and we're facing elimination at this point."
"There remains significant pride at stake and we will certainly approach it with that mindset," he continued.
"The challenge has been tough. Australia is a formidable team. It was inevitably tough coming here against them. They were the front-runners and they've proven why."
Ollie Pope's Place Under Scrutiny
Although Crawley's innings in Adelaide likely secures questions about his short-term place in the England team, Ollie Pope appears under immense pressure for his position in the Melbourne Test on Boxing Day.
Pope fell for 17 in England's second knock on Saturday, extending his modest returns versus the old enemy.
In sixteen Ashes knocks, the Surrey man has failed to score a fifty and boasts an average of just 17.62.
Only one other England player in over a century – Dennis Amiss – has played as many times in the top six in the Ashes and recorded a lower average.
However, Crawley said any notion his teammate is being scrutinised comes from "you guys" – referring to the press – "and not within the team."
"We all know how good of a player he is," said he. "Ollie has enjoyed a good year if I'm honest."
"He has produced some really good knocks. This is talk externally. There's no discussion of that nature regarding Pope in the camp," he concluded.
