Fast bowler Atkinson Compounds the English team's Injury Problems.
'Significant concern' for England after Atkinson is forced off suffering a hamstring problem.
The pace bowler added to the injury concerns plaguing England when he left the field during Saturday's play of the Boxing Day Test versus the Australians.
The pace bowler pulled up with his hamstring after the final ball of the fourth over on Saturday.
Team management indicated the 27-year-old had experienced "tightness" and required time away from the action for further assessment "over the next few hours".
The final Test of the series at the SCG begins on Sunday, 4 January.
The English side has already lost key quicks Mark Wood due to knee trouble and Jofra Archer to a side strain on this Ashes tour.
Matthew Fisher was brought into the squad as cover for Wood.
Atkinson struggled early in the series, taking just a handful of scalps.
He was dropped for the Adelaide match, before being recalled for the Melbourne Test to fill the void.
The county bowler improved at the MCG, taking two wickets during the host's first knock, then making 28 as a batsman being one of only three England players to get into double digits.
After bowling one over at the end of day one, he resumed on Saturday morning and removed Scott Boland taken by the wicketkeeper.
Yet, towards the conclusion of the fifth over, he sent down a variation to Travis Head and suddenly grabbed at his leg.
The English bowler was brought back for the Boxing Day Test having missed the previous Test.
