The Australian skipper 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 have a crucial role in the forthcoming Ashes series.
Speculation had been growing that the veteran bowler might miss the series due to a stress fracture in his back that was still troubling him.
Initial reports from team management suggested no official announcement had been made regarding Cummins' participation, with the extended contest set to start on 21 November in the WACA.
He revealed that the captain is progressing and was "optimistic" about the likelihood of taking part.
"We're aware that time is getting short and various factors around that, not just the physical problem, but further aspects," the selector added.
"The outlook is good. [We are] really confident that he's going to play a major part. Hopefully starting in Perth. If not, we'll adjust."
Past Concerns
He was sidelined Australia's limited-overs series against India and New Zealand in the previous weeks after medical tests showed a lower back issue.
He has a history of recurring issues, with setbacks in 2012-13, 2013-14 and 2015-16 causing him to miss multiple domestic campaigns in four years.
Cummins stated he would be proactive in his approach in his recovery plan to secure his spot for the Ashes.
He mentioned that there was no confirmation if Cummins had begun bowling as part of his recovery but conceded it was "pressing" for him to regain fitness for the first Test.
Alternative Arrangements
In case of absence, former captain Steve Smith will take over the captaincy.
Versatile player Green was withdrawn recently from Australia's squad for their one-day international series against the subcontinent side as a precautionary measure because of an abdominal issue.
He labeled it as a "minor" injury and stated that he'll feature in the domestic first-class competition, so will be "in a good place to resume bowling."
"Extensive planning has gone into creating the schedule for him to be available for the first Test as an all-rounder," the selector detailed.
"Originally, he'd only feature in the starting games anyway. His aggressive style the cricket bat in white-ball cricket, if it causes any delay for 24 more hours, we just made the decision to approach this more conservatively."
