The English opening batter Crawley suggested he had no knowledge of statements from skipper Ben Stokes about the dressing room as no place for "weak men".
Stokes made those words in multiple conversations following his team's defeat in the second Ashes series against the Australians earlier this month.
Ahead of the third Test, where England are staring at a series loss with a match to spare, the captain stated he had allowed his sentiment to "circulate freely" among the squad.
"I have completed the necessary discussions over the past two days that I required," said the England leader.
But, following Crawley made 85 on the penultimate day in Adelaide, he commented: "I didn't see that."
"I wasn't actively searching for it. We take everything that is said in the media with some skepticism," Crawley continued.
Frank Discussions and Consistent Messaging
The captain issued his "fragile individuals" comment after England suffered a loss in the second Test to fall two matches behind.
The team subsequently went on a holiday to Noosa in the gap between the second and third Tests.
Prior to the Adelaide contest, Stokes said his players had held "raw" talks and he had urged them to "display some fight" in their battle to stay alive in the Ashes battle.
Nevertheless, Crawley asserted the guidance from the captain and coach McCullum had remained consistent with their prior three years in charge.
"The atmosphere has been extremely upbeat, the same as always," said Crawley. "It's just trying to be optimistic, play our way, with lots of freedom. It felt like we could do something special going into this Test."
The Hosts On the Verge of Historic Series Victory
The opener's wicket late on Saturday came during a crucial three-wicket burst by Australia off-spinner Lyon.
Lyon's three wickets in 20 deliveries – including the wickets of Brook and Stokes himself – left England 207-6 chasing a notional total of 435.
Consequently, Australia need just four more wickets on the last day to secure an unassailable 3-0 advantage after three Tests.
Defeat will extend the English team's drought in Australia to 18 Tests and condemn them to a fourth successive overseas Ashes series defeat.
The current battle will be completed in only eleven days of play – with England losing the first two Tests in rapid time each.
Not since 1921, when Australia sealed victory in England in eight days, has the outcome of the Ashes urn been determined so quickly. Australia have also triumphed in eleven days on two other occasions in the 21st century.
"It's disappointing," said the batsman. "We came here to regain the Ashes and now we are facing elimination now."
"There will still be plenty to play for and we'll certainly approach it with that mindset," Crawley added.
"The challenge has been tough. They're a very, very good side. It was inevitably tough coming here against them. They were the favourites coming in to it they've proven why."
Ollie Pope's Place In Question
While the opener's innings in Adelaide probably answers questions about his immediate future in the side, Ollie Pope looks under immense pressure for his position in the Melbourne Test on Boxing Day.
The Surrey batsman was out for 17 in the team'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 boasts an average of just 17.62.
Only one other England player since 1900 – Amiss – has featured as many times in the top six in Ashes Tests and recorded a poorer average.
But, Crawley insisted any notion his teammate is under the microscope originates with "the media" – meaning the press – "not inside the camp."
"We all know how good of a player he is," said he. "He has had a good year if I'm honest."
"He has produced several excellent innings. This is noise from the outside. There is no discussion like that on Ollie in the camp," he concluded.
