Paceman Atkinson Adds to the English team's Fitness Concerns.
'Serious blow' for the English camp as Atkinson goes off due to a hamstring issue.
The English seamer added to the injury concerns plaguing England when he left the field early on day two of the fourth Ashes Test versus the Australians.
Atkinson pulled up with his left leg post-delivery of the fourth over on Saturday.
The touring camp indicated the 27-year-old felt some "soreness" and was to take time on the sidelines to undergo evaluation "in the coming hours".
The final Test of the tour at the SCG gets underway at the end of the week.
The English side has been without strike bowlers Mark Wood to a knee injury and Jofra Archer with an abdominal strain on this Ashes tour.
Matthew Fisher was called up as cover for Wood.
Atkinson struggled during the first two matches, managing only three wickets.
He was omitted for the Adelaide match, only to be brought back for the Melbourne Test to fill the void.
Atkinson performed better in the fourth Test, claiming a couple of wickets during the host's first knock, before adding 28 with the bat being one of only three England players to get into double digits.
After bowling one over late on the first day, he came back on Saturday morning and dismissed the nightwatchman edging to the keeper.
However, on the final ball of that over, he bowled 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 having missed the previous Test.
