The English opening batter Crawley suggested he had no knowledge of comments from skipper Ben Stokes about the dressing room as no place for "those lacking fortitude".
The all-rounder delivered those words in several conversations in the wake of his team's loss in the second Ashes series against Australia previously.
Ahead of the Adelaide Test, where England now face a series loss with a match to spare, the captain stated he had allowed his sentiment to "drift around" within the playing group.
"I have completed the necessary discussions in recent days that I required," said Stokes.
However, following Crawley scored 85 on the fourth day in Adelaide, he commented: "I missed those remarks."
"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
Stokes issued his "weak men" observation after England suffered a loss in the second Test to go two matches behind.
The England squad subsequently went on a holiday to a Queensland resort between the second and the upcoming Tests.
Prior to this match, Stokes said his players had held "raw" conversations and he had asked them to "show a bit of dog" in their battle to remain in contention in the series.
Nevertheless, Crawley asserted the messaging from Stokes and coach McCullum had remained in line with their prior three years in leadership.
"It's been very positive, unchanged," noted the opener. "The focus is on maintaining positivity, play our way, with lots of freedom. We believed we were capable of something special entering this game."
Australia On the Verge of Rapid Series Victory
The opener's wicket late on Saturday was part of a decisive triple-strike 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 total of 435 runs.
This means, Australia require four wickets on the last day to secure an unassailable three-nil advantage with three matches played.
A loss will extend England's winless run in Australia to 18 consecutive matches and ensure a fourth successive overseas Ashes series loss.
This series will be completed in just eleven days of cricket – after England losing the first two Tests in rapid time respectively.
Not since 1921, when Australia sealed victory in the UK in eight days, has the outcome of the urn been decided more swiftly. The hosts have also triumphed in eleven days on two other occasions in the modern era.
"This is disappointing," said Crawley. "Our goal was to regain the Ashes and now we are facing elimination now."
"There remains plenty to play for and we'll certainly approach it like that," he continued.
"The challenge has been tough. Australia is a formidable side. It was inevitably tough coming here against them. They entered as the front-runners coming in to it have demonstrated their quality."
Ollie Pope's Place Under Scrutiny
While the opener's performance in Adelaide likely secures doubts about his immediate place in the England team, 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 innings on day four, adding to his poor record against the old enemy.
Across 16 Ashes innings, 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 – Amiss – has played as many times in the top six in the Ashes and returned a poorer average.
However, the opener said any notion his teammate is being scrutinised originates with "you guys" – referring to the press – "and not within the team."
"We all know how good of a player he is," said he. "He has had a good year if I'm honest."
"He has played several excellent innings. It is talk from the outside. There's no discussion like that regarding Pope amongst the players," he concluded.
