The Australian skipper has claimed 309 wickets in 71 five-day games with an stellar bowling average.
Australia's selection chief George Bailey has stated that skipper Cummins will have a crucial role in the upcoming England-Australia contest.
Speculation had been growing that Cummins might sit out due to a ongoing back issue that had not yet healed.
Initial reports from team management suggested no definitive call had been made regarding Cummins' participation, with the five-Test series scheduled to begin on November 21 in Western Australia.
He revealed that Cummins is "building up" and felt positive about the prospects of taking part.
"We know that the window is narrowing and various factors involved, not only the back issue, but further aspects," Bailey remarked.
"We're encouraged. [We are] really confident that he will feature a significant role. Ideally starting in Perth. Should that not happen, we'll adjust."
Injury History
He was sidelined the white-ball matches against India and New Zealand last month after scans revealed a lower back issue.
Previous incidents include of spinal problems, with recurrences in multiple past seasons leading to absences from three Australian summers in a limited period.
Cummins stated he would be proactive in his approach in his recovery plan to make the squad for the Ashes.
The selector indicated that it was unclear if he had started his bowling workouts as part of his comeback but conceded it was "becoming urgent" for him to regain fitness for the opener.
Backup Options
Should Cummins not be fit, former captain Steve Smith will lead the side.
Versatile player Green was excluded lately from the ODI lineup for their ODI contests against India as a preventive step because of discomfort in his torso.
The selector characterized it as a "small issue and stated that he'll feature in the state-level matches, so will be "well-prepared to deliver overs."
"We put so much time has gone into building out the plan for him to participate for the initial game as an dual-role player," he elaborated.
"His involvement was limited to the initial matches in any case. The way he swings the bat in limited-overs, should it hinder progress for another day, we opted to approach this more conservatively."
