Skipper Pat Cummins has revealed that his involvement in the first Ashes Test appears unlikely due to ongoing fitness concerns.
Media speculation from Australia had suggested that Cummins might be ruled out of the whole series, though the pace bowler himself has now provided a more comprehensive update on his condition.
The 32-year-old has been struggling with a spinal issue that has prevented his participation since his last professional game in July.
Although Cummins has restarted running exercises, he has yet to begin bowling as part of his rehabilitation program.
"It's difficult to assign a percentage on it, but I'd say probably more doubtful than certain," stated Cummins. "We get into begins next week, so approximately a couple of weeks away from actually putting on the spikes and bowling out on turf."
Australia coach Andrew McDonald had earlier suggested that Cummins would require a bare minimum of four weeks of net sessions to have any chance of playing in the first Test, set to begin on November 21.
Cummins supported this assessment, clarifying: "You'd want at least probably a month in the nets. If you play a Test match, you want to make certain you're capable to bowl 20 overs in a day without concern."
Given the compressed timeframe, there are also doubts about Cummins' availability for the following match in Brisbane on December 4.
Should Cummins be unfit, former captain Steve Smith is expected to captain the side, with Scott Boland possibly stepping in in the bowling attack.
Australia have held the Ashes urn since 2018, while England are without a Test win in Australia since 2011.
Cummins' current injury concerns mirror challenges from earlier in his successful career. He made his Test debut as an 18-year-old in 2011 against South Africa, becoming the second-youngest player to take a five-wicket haul in an innings at that time.
However, his impressive debut proved to be a false dawn, as Cummins experienced six years before his next match due to repeated stress fractures in his spine.
When fit, Cummins has established himself as one of cricket's premier fast bowlers. The 32-year-old has taken 309 Test dismissals at an impressive average of 22.10.
His record in Australia is even more formidable, with 177 wickets at 19.92, while he has claimed 91 wickets against England in just 19 matches.
In the latest Ashes series in 2023, Cummins played in all five Tests, taking 18 wickets and establishing his importance to the Australian side.
As captain, Cummins enjoyed a successful 2023, taking six wickets in Australia's triumphant World Test Championship final and starring in their 50-over World Cup final win against India.
He remains the only captain in Test history to win the World Test Championship, World Cup, and an Ashes series.
England also face their own fitness concerns with captain Ben Stokes, who has been troubled by a shoulder injury since the Test series against India.
Both teams will be assessing their key players closely as the highly anticipated Ashes series approaches.
