Fast bowler Atkinson Compounds the English team's Fitness Concerns.
'Major setback' for the touring side as Atkinson is forced off suffering a hamstring problem.
Gus Atkinson increased the fitness woes of the England squad after leaving the playing area early on day two in the Melbourne Test versus the Australians.
Atkinson pulled up with his left leg after the final ball that he bowled at the MCG.
Team management stated the 27-year-old felt some "soreness" and would spend time off the field in order to be assessed "in the coming hours".
The concluding match of the series at the SCG begins this coming Sunday.
The English side has already lost fast bowlers Mark Wood to a knee injury and another paceman because of a side injury on this Ashes tour.
Matthew Fisher was called up to provide backup.
His form was underwhelming early in the series, managing only a handful of scalps.
He was left out from the previous Test, only to be brought back for the Boxing Day match in the playing XI.
Surrey's Atkinson performed better in the fourth Test, bagging two scalps with the ball, and scoring 28 runs as a batsman as one of just three teammates who passed ten runs.
Following a brief spell late on the first day, he returned on Saturday morning and had nightwatchman edging to the keeper.
Unfortunately, on the final ball of his spell, he bowled a change of pace to Travis Head and immediately felt at his leg.
The English bowler was brought back for the Melbourne match having missed the Adelaide game.
