Seamer Atkinson Compounds the English team's Fitness Concerns.
'Major setback' for the English camp after Atkinson leaves the field due to a hamstring issue.
The pace bowler added to the injury concerns plaguing England upon exiting the ground during Saturday's play of the fourth Ashes Test versus the Australians.
The right-arm seamer experienced discomfort in his left hamstring immediately following a delivery in his spell on Saturday.
The England team stated Atkinson had experienced "tightness" and required time on the sidelines in order to be assessed "in the coming hours".
The concluding match of the tour in Sydney starts on Sunday, 4 January.
The English side has been without key quicks Mark Wood with a knee problem and another paceman with an abdominal strain during this series.
A replacement bowler was brought into the squad as injury reinforcement.
The seamer had a tough time during the first two matches, taking just a handful of scalps.
He was omitted from the previous Test, only to be brought back for the fourth Test to fill the void.
The county bowler performed better in the fourth Test, bagging two scalps during the host's first knock, and scoring 28 runs with the bat being one of only three England players to get into double digits.
Post a single over at the end of day one, he resumed for the second day's play and dismissed the nightwatchman edging to the keeper.
However, at the end of his spell, he delivered a change of pace to Travis Head and promptly felt for his hamstring.
The English bowler was recalled for the Boxing Day Test after being left out the Adelaide game.
