The Australian skipper has taken 309 Test scalps in 71 five-day games with an stellar bowling average.
Australia's selection chief George Bailey has confirmed that skipper Cummins will be a central figure in the upcoming historic rivalry.
Speculation had been growing that Cummins might miss the series due to a stress fracture in his back that was still troubling him.
Initial reports from team management suggested no final decision had been made regarding his involvement, with the Test matches scheduled to begin on November 21 in Western Australia.
Bailey expressed that his recovery is on track and remained hopeful about his chances of being involved.
"It's clear that the window is narrowing and there are permutations around that, not only the physical problem, but further aspects," Bailey remarked.
"We're encouraged. [We are] really confident that he's going to play a significant role. Hopefully from the opening match. Otherwise, then we'll pick it up."
Past Concerns
The captain missed the ODI and T20 games against India and New Zealand last month after examinations confirmed a lumbar bone stress.
There is a track record of spinal problems, with setbacks in multiple past seasons leading to absences from three Australian summers in a limited period.
Cummins stated he would be bold in recovery efforts in his rehabilitation process to make the squad for the Ashes.
The selector indicated that there was no confirmation if Cummins had begun bowling as part of his comeback but acknowledged it was "becoming urgent" for him to regain fitness for the opener.
Alternative Arrangements
Should Cummins not be fit, former captain Steve Smith will assume leadership.
All-rounder Cameron Green was excluded lately from Australia's squad for their limited-overs matches against India as a preventive step because of soreness in his side.
He labeled it as a "small issue and stated that Green will play in the Sheffield Shield, so will be "in a good place to deliver overs."
"Considerable effort has gone into creating the schedule for him to be available for the first Test as an dual-role player," Bailey explained.
"His involvement was limited to the starting games regardless. His aggressive style the willow in shorter formats, even if it just sets him back for another day, we opted to take a cautious route."
