Fast bowler Atkinson Compounds England's Fitness Concerns.
'Major setback' for England after Atkinson leaves the field due to a hamstring issue.
The English seamer added to the fitness woes of the England squad upon exiting the ground during Saturday's play of the fourth Ashes Test against Australia.
The pace bowler experienced discomfort in his left hamstring post-delivery of the fourth over on Saturday.
Team management indicated Atkinson felt some "soreness" and was to take time away from the action in order to be assessed "in the coming hours".
The concluding match of the tour in Sydney gets underway at the end of the week.
England have previously lost strike bowlers Mark Wood to a knee injury and another paceman to a side strain on this Ashes tour.
A replacement bowler was brought into the squad to provide backup.
His form was underwhelming in the opening two Tests, managing only a handful of scalps.
He was left out of the third Test, only to be brought back for the fourth Test in the playing XI.
The county bowler performed better in the fourth Test, taking two wickets with the ball, then making 28 as a batsman as one of just three England players to reach double figures.
Post a single over in Australia's second innings, he came back for the second day's play and removed Scott Boland edging to the keeper.
Unfortunately, at the end of that over, he delivered a variation to the batsman and immediately felt at his leg.
Gus Atkinson was brought back for the fourth Ashes Test after being left out the previous Test.
