Seamer Atkinson Compounds the English team's Fitness Problems.
'Serious blow' for the English camp after Atkinson leaves the field due to a hamstring issue.
The pace bowler increased the injury concerns plaguing England after leaving the field during Saturday's play of the fourth Ashes Test against Australia.
The pace bowler experienced discomfort in his left leg post-delivery of the fourth over during the morning session.
The touring camp reported Atkinson had experienced "tightness" and was to take time on the sidelines in order to be assessed "during the day".
The concluding match of the tour at the SCG gets underway this coming Sunday.
The visitors have already lost key quicks Mark Wood due to knee trouble and Jofra Archer because of a side injury during this series.
A replacement bowler was called up as cover for Wood.
Atkinson struggled early in the series, managing only three wickets.
He was omitted from the previous Test, before being recalled for the fourth Test in the playing XI.
The county bowler showed better form in Melbourne, claiming a couple of wickets with the ball, and scoring 28 runs as a batsman as one of just three English batsmen to reach double figures.
After bowling one over late on the first day, he came back on Saturday morning and removed Scott Boland edging to the keeper.
However, at the end of that over, he bowled a slower ball to the batsman and promptly felt for his hamstring.
The English bowler returned to the side for the Melbourne match having missed the previous Test.
