Australian wicketkeeper Alex Carey revealed he felt he had edged the ball when he was given not out on DRS during day one of the third Ashes Test against England.
After surviving on 72, Carey went on to make a superb 106 to guide the Australians post 326-8 at the stumps in the Adelaide Oval.
Australia were 245-6 when Carey attempted a cut to the bowling of Josh Tongue.
England were convinced they had a wicket, thinking they had detected an edge, but umpire Ahsan Raza was unmoved.
After captain Ben Stokes referred the on-field call, the replay examined by third umpire Chris Gaffaney showed a significant spike however this registered before the ball had reached the bat.
Gaffaney further stated he was of the opinion there was a clearance between bat and ball.
As a result, Carey was allowed to continue.
"I thought there was a feather or some sort of noise when it passed the bat," said Carey.
"Had I been given out, I likely would have reviewed, but without much conviction. There was a definite noise."
Discussion has swirled about 'the sound wave technology' during the Ashes contest after a number of dubious calls.
Bowling coach David Saker suggested England may escalate this most recent incident further with match referee Jeff Crowe.
"I don't think we've done anything about it so far but after today, maybe that might go a bit further," Saker said.
"It's been a worry for us all series long. It's disappointing that this is a post-play discussion. That's the situation."
The ton was his maiden in Test cricket against England.
It was also an heartfelt moment for Carey, whose father died in September. His spouse was emotional in the crowd as the batter celebrated by glancing upward.
"A hundred on home soil with loved ones present is unforgettable," stated Carey.
"The reason for my look upwards is clear. I'm trying not to tear up. It was truly wonderful."
Carey has been at the centre of Ashes debate before.
He was the keeper who famously stumped Jonny Bairstow at Lord's in the 2023 series, leading to a febrile final day.
On his reprieve he added: "The technology clearly wasn't synchronized. That's cricket - you get the rub of the green sometimes."
"Perhaps luck was on my side."
