The English opening batter Crawley has indicated he was not familiar with statements from skipper Ben Stokes about the dressing room as no place for "weak men".
The all-rounder delivered this message in multiple conversations in the wake of his team's defeat in the second Ashes against Australia earlier this month.
In the lead-up to the Adelaide Test, where the visitors are staring at defeat at the earliest opportunity, the captain stated he had let his message to "drift around" among the playing group.
"I've done all the talking over the past two days that I required," said the England leader.
But, following the opener made 85 on the fourth day in the third Test, he stated: "I missed those remarks."
"I didn't see and wasn't really looking out for it. We take everything that is said in the press with a pinch of salt," he added.
Raw Conversations and Steady Philosophy
The captain made the "fragile individuals" observation subsequent to his side were beaten in Brisbane to go 2-0 down.
The team subsequently went on a break to Noosa in the gap between the second and third matches.
Before the Adelaide contest, Stokes revealed his players had held "honest" talks and he had asked them to "display some fight" in their battle to stay in contention in the Ashes battle.
Nevertheless, the Kent batsman asserted the messaging from the captain and head coach McCullum had stayed in line with their previous three years in charge.
"The atmosphere has been very positive, unchanged," said the opener. "The focus is on maintaining positivity, play our way, with lots of freedom. We believed we could do an extraordinary feat going into this game."
Australia On the Verge of Historic Series Victory
The opener's wicket on day four was part of a crucial three-wicket burst by Australia off-spinner Lyon.
The spinner's triple strike in 20 deliveries – including the wickets of Harry Brook and Ben Stokes – meant the chasing side 207-6 in pursuit of a notional total of 435 runs.
This means, Australia require four wickets on Sunday's final day to move to an insurmountable 3-0 advantage after three Tests.
Defeat would prolong England's drought in Australia to 18 Tests and ensure a fourth successive overseas Ashes loss.
The current battle is set to be decided in only 11 days of play – after England losing the initial matches in rapid time respectively.
Not since 1921, when Australia completed a series win in the UK in eight days, has the outcome of the urn been determined more swiftly. Australia have also triumphed in eleven days on two other occasions in the modern era.
"This is disappointing," admitted the batsman. "We came here to regain the Ashes and we're facing elimination now."
"There remains plenty to play for and we will definitely view it with that mindset," Crawley added.
"The challenge has been tough. Australia is a formidable team. It was always going to be tough coming here against them. They were the favourites coming in to it have demonstrated their quality."
Pope's Position Under Scrutiny
Although the opener's innings in the third Test probably answers questions about his immediate place in the side, Ollie Pope appears under threat 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 modest returns against the old enemy.
In sixteen Ashes knocks, the Surrey man has failed to score a half-century and boasts an average of just 17.62.
A solitary other England player since 1900 – Amiss – has featured 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 "the media" – referring to the journalists – "and not within the team."
"The squad is fully aware of his considerable talent," said he. "Ollie has enjoyed a productive year to be frank."
"He has played several excellent innings. It is noise from the outside. There is no discussion like that regarding Pope in the camp," he concluded.
