Seamer Atkinson Compounds the English team's Injury Worries.
'Serious blow' for the English camp after Atkinson goes off with a hamstring injury.
The pace bowler increased England's injury problems when he left the field during Saturday's play in the Melbourne Test versus the Australians.
Atkinson pulled up with his hamstring post-delivery that he bowled on Saturday.
The touring camp reported Atkinson reported "discomfort" and was to take time on the sidelines to undergo evaluation "during the day".
The concluding match in this Ashes battle at the SCG gets underway at the end of the week.
England have previously lost fast bowlers Mark Wood with a knee problem and Jofra Archer with an abdominal strain during this series.
Matthew Fisher was called up as cover for Wood.
Atkinson struggled early in the series, claiming a mere a handful of scalps.
He was dropped for the Adelaide match, then recalled for the Melbourne Test as Archer's replacement.
Surrey's Atkinson showed better form in Melbourne, bagging two scalps in Australia's first innings, before adding 28 as a batsman as one of just three teammates who passed ten runs.
After bowling one over late on the first day, he came back the next day and dismissed the nightwatchman edging to the keeper.
Yet, on the final ball of that over, he delivered a change of pace to the batsman and promptly felt for his hamstring.
The English bowler returned to the side for the fourth Ashes Test after being left out of the third.
