Seamer Atkinson Compounds England's Injury Problems.
'Major setback' for the English camp after Atkinson is forced off with a hamstring injury.
The English seamer further complicated the fitness woes of the England squad upon exiting the field on the second morning of the Boxing Day Test versus the Australians.
The pace bowler experienced discomfort in his left leg after the final ball that he bowled on Saturday.
The England team indicated Atkinson had experienced "tightness" and required time on the sidelines to undergo evaluation "in the coming hours".
The series decider of the tour at the SCG gets underway on Sunday, 4 January.
The English side has already lost key quicks one seamer with a knee problem and another paceman to a side strain during this series.
Matthew Fisher was added to the party to provide backup.
The seamer had a tough time early in the series, claiming a mere a handful of scalps.
He was dropped of the third Test, then recalled for the Melbourne Test in the playing XI.
Atkinson performed better in the fourth Test, bagging two scalps with the ball, and scoring 28 runs as a batsman being one of only three England players who passed ten runs.
Following a brief spell at the end of day one, he came back the next day and dismissed the nightwatchman Scott Boland caught behind.
However, towards the conclusion of that over, he sent down a change of pace to Travis Head and immediately felt for his hamstring.
Gus Atkinson was brought back for the Melbourne match after being left out of the third.
