Fast bowler Atkinson Compounds the English team's Fitness Worries.
'Significant concern' for England after Atkinson goes off suffering a hamstring problem.
The English seamer further complicated the fitness woes of the England squad upon exiting the ground early on day two in the Melbourne Test against Australia.
Atkinson pulled up with his left hamstring post-delivery that he bowled during the morning session.
The England team reported Atkinson had experienced "tightness" and was to take time away from the action in order to be assessed "in the coming hours".
The concluding match of the series at the SCG gets underway on Sunday, 4 January.
The English side has been without strike bowlers one seamer with a knee problem and another paceman because of a side injury on this Ashes tour.
Matthew Fisher was added to the party as injury reinforcement.
His form was underwhelming early in the series, managing only a handful of scalps.
He was dropped of the third Test, before being recalled for the Melbourne Test to fill the void.
Atkinson performed better in the fourth Test, taking two wickets with the ball, and scoring 28 runs as a batsman as one of just three English batsmen to get into double digits.
After bowling one over at the end of day one, he returned for the second day's play and had nightwatchman Scott Boland caught behind.
However, on the final ball of that over, he delivered a variation to Travis Head and immediately felt his left hamstring.
Atkinson was brought back for the fourth Ashes Test after being left out of the third.
