England opening batter Crawley has indicated 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 this message in multiple interviews following his team's defeat in the second Ashes versus the Australians earlier this month.
In the lead-up to the Adelaide Test, where the visitors are staring at defeat at the earliest opportunity, Stokes stated he had allowed his message to "drift around" among the playing group.
"I have completed the necessary discussions in recent days that I needed to have done," said the England leader.
But, following the opener scored a knock of 85 on the penultimate day in the third Test, he stated: "I missed those remarks."
"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 Steady Philosophy
Stokes made the "weak men" observation after his side were beaten in the second Test to go two matches behind.
The team subsequently took a holiday to Noosa between the second and third Tests.
Prior to this match, Stokes revealed his players had held "honest" conversations and he had asked them to "show a bit of dog" in their effort to remain in contention in the series.
Yet, the Kent batsman stated the messaging from the captain and coach McCullum had stayed consistent with their prior three years in charge.
"It's been very positive, the same as always," said Crawley. "It's just trying to be optimistic, play our way, with great liberty. It felt like we could do an extraordinary feat entering this game."
The Hosts On the Verge of Rapid Series Victory
Crawley's wicket late on Saturday came during a decisive triple-strike by Australia spinner Nathan Lyon.
The spinner's three wickets in 20 deliveries – including the wickets of Brook and Ben Stokes – left the chasing side 207-6 chasing a daunting total of 435.
Consequently, the home team require four wickets on Sunday's final day to secure an insurmountable 3-0 advantage after three matches played.
A loss would prolong England's winless run in this country to 18 Tests and ensure a fourth straight overseas Ashes loss.
The current battle is set to be decided in just eleven days of cricket – with England fell the initial matches in two and four days each.
The last time 1921, when the Australians completed a series win in the UK in eight days, has the destination of the urn been determined more swiftly. Australia have also won in eleven days on two other instances in the modern era.
"It's disheartening," admitted Crawley. "We came here to win the Ashes and now we are facing elimination at this point."
"There remains plenty to play for and we'll certainly approach it with that mindset," he continued.
"The challenge has been tough. They're a very, very good team. It was inevitably hard coming here against them. They were the front-runners coming in to it they've proven why."
Ollie Pope's Position In Question
Although the opener's performance in the third Test likely secures doubts about his immediate place in the England team, Pope looks under threat for his spot in the fourth Test on Boxing Day.
The Surrey batsman was out for 17 runs in the team's second innings on day four, adding to his poor record against Australia.
In 16 Ashes innings, the Surrey man has never made a fifty and averages just 17.62.
Only one other English batsman in over a century – Amiss – has featured an equal number of innings in the top order in Ashes Tests and returned a lower average.
But, the opener insisted any suggestion his teammate is being scrutinised originates with "you guys" – referring to the press – "not inside the camp."
"The squad is fully aware how good of a player he is," said Crawley. "Ollie has enjoyed a productive year to be frank."
"He has played several excellent innings. This is noise from the outside. There's no discussion of that nature regarding Pope amongst the players," he concluded.
