Hazlewood cleared from fitness concerns however Sean Abbott ruled out of Test
The bowler has claimed 295 wickets with an average of 24.21 across 76 Test matches
Hazlewood received clearance to become part of Australia's squad for the initial Test against England following fitness concerns, although compatriot Abbott is unavailable
The two experienced hamstring issues during their match for New South Wales versus Victoria during Sheffield Shield action recently
Tests indicated Hazlewood (34) escaped tissue injury. Abbott, 33, who hasn't played Tests, has a significant hamstring issue
Team captain Cummins will miss the first Test, commencing later this month, meaning the absence of a key pace option in Hazlewood could have proven a major blow
Abbott would have been doubtful to feature in Perth, while Hazlewood will combine Mitchell Starc and Scott Boland as the primary pace attack
Cummins, currently healing from a back injury, is expected to be likely to comeback for the second Test beginning December 4 in Brisbane
Batsman Steve Smith will captain the side during the captain's recovery
Similar to most Australian cricketers, the bowler took part in recent matches of state games ahead of the Ashes
Prior to recently, he had not played a first-class match representing NSW for over twelve months
He noticed discomfort in his hamstring near the conclusion of Victoria's second innings during the match and left the field as a precaution
Neither Hazlewood nor Abbott batted in New South Wales' second innings in a losing cause in a substantial margin
"We're a week away from the Test series - typically prefer precautionary measures," commented Cummins
"The medical staff sought to identify the exact situation ahead of risking that could worsen anything worse"
"He seldom shows him upbeat, therefore it was positive to witness his smile"
"He's aware of his condition thoroughly. I think he was slightly anxious (and) wanted to get it checked out"
Abbott earned 57 caps with the national team in ODI and T20 cricket
The uncapped Brendan Doggett is the other seamer within the team, providing cover for the primary fast bowlers
