The English opener Crawley suggested he had no knowledge of comments from skipper Ben Stokes regarding the dressing room as no place for "weak men".
Stokes delivered this message in multiple conversations following his team's loss in the second Ashes series against the Australians earlier this month.
Ahead of the third Test, where the visitors are staring at a series loss with a match to spare, the captain noted he had let his message to "drift around" within the squad.
"I have completed the necessary discussions in recent days that I needed to have done," said Stokes.
However, after Crawley made 85 on the penultimate 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," Crawley continued.
Raw Conversations and Consistent Messaging
The captain made the "fragile individuals" comment after England were beaten in Brisbane to go two matches behind.
The England squad subsequently went on a break to a Queensland resort in the gap between the second and the upcoming Tests.
Prior to the Adelaide contest, Stokes said his team had held "raw" conversations and he had urged them to "show a bit of dog" in their effort to stay alive in the series.
Nevertheless, Crawley stated the guidance from the captain and head coach Brendon McCullum had stayed consistent with their prior tenure in charge.
"The atmosphere has been very positive, the same as always," said Crawley. "The focus is on maintaining positivity, playing our brand, with lots of freedom. It felt like we were capable of an extraordinary feat entering this Test."
The Hosts On the Verge of Historic Ashes Triumph
The opener's wicket on day four was part of a crucial triple-strike by Australia spinner Lyon.
The spinner's triple strike in a short spell – including the wickets of Brook and Ben Stokes – meant England 207-6 in pursuit of a notional target of 435 runs.
This means, the home team require just four more wickets on the final day to secure an unassailable 3-0 lead with three Tests.
A loss would prolong England's drought in this country to 18 consecutive matches and ensure a fourth straight away Ashes loss.
The current battle will be completed in just 11 days of play – with England fell the initial matches in two and four days respectively.
The last time 1921, when Australia completed a series win in England in eight days, has the outcome of the Ashes urn been determined more swiftly. The hosts have also won in 11 days on two other occasions in the 21st century.
"This is disheartening," said Crawley. "Our goal was to regain the Ashes and now we are staring down the barrel at this point."
"There remains significant pride at stake and we'll certainly approach it with that mindset," Crawley added.
"The challenge has been tough. Australia is a very, very good team. It was inevitably hard coming here to face them. They entered as the favourites and they've proven why."
Ollie Pope's Place In Question
While the opener's innings in the third Test probably answers questions about his immediate future in the England team, Ollie Pope appears under immense pressure for his spot in the fourth Test on Boxing Day.
The Surrey batsman was out for 17 in the team's second knock on Saturday, extending his poor record versus Australia.
Across 16 Ashes innings, the Surrey man has failed to score a fifty and averages just 17.62.
A solitary other England player in over a century – Amiss – has played as many times in the top six in Ashes Tests and returned a lower average.
However, the opener insisted any notion his teammate is being scrutinised originates with "the media" – meaning the journalists – "not inside the camp."
"The squad is fully aware of his considerable talent," said Crawley. "He has had a good year if I'm honest."
"He has played several excellent innings. It is talk externally. There is no chat of that nature on Ollie amongst the players," he finished.
