The pace bowler has taken 309 Test scalps in 71 appearances with an average of 22.10.
Australia's chief selector George Bailey has declared that skipper Cummins will play a "major part" in the forthcoming Ashes series.
Rumors had circulated that the 32-year-old might miss the series due to a ongoing back issue that was still troubling him.
Initial reports from the squad suggested no definitive call had been made regarding his involvement, with the five-Test series kicking off on the 21st of November in the WACA.
The selector shared that his recovery is on track and felt positive about the likelihood of taking part.
"We're aware that the window is narrowing and multiple considerations around that, not just his injury, but other factors as well," the selector added.
"We're encouraged. [We are] really confident that he'll participate in a key capacity. Ideally starting in Perth. Should that not happen, we'll reassess."
Past Concerns
He was sidelined the white-ball matches against both Asian and Trans-Tasman rivals last month after medical tests showed a lower back issue.
He has a history of recurring issues, with setbacks in several earlier campaigns causing him to miss three Australian summers in a limited period.
The bowler mentioned he would be bold in recovery efforts in his rehabilitation process to secure his spot for the contest.
The selector indicated that it was unclear if Cummins had begun bowling as part of his recovery but conceded it was "becoming urgent" for him to recover fully for the opener.
Contingency Plans
If he's unavailable, former captain Steve Smith will assume leadership.
Versatile player Green was recently pulled out from the national team for their limited-overs matches against the subcontinent side as a precautionary measure because of discomfort in his torso.
Bailey described it as a "small issue and confirmed that Green will play in the state-level matches, so will be "ideally positioned to deliver overs."
"We put so much time has gone into building out the plan for him to be available for the first Test as an batting and bowling option," Bailey explained.
"Originally, he'd only feature in the first two ODIs anyway. How he handles the bat in limited-overs, if it causes any delay for 24 more hours, we opted to approach this more conservatively."
