Fast bowler Atkinson Adds to England's Injury Worries.
'Major setback' for the touring side as Atkinson leaves the field suffering a hamstring problem.
The English seamer increased the fitness woes of the England squad upon exiting the field early on day two of the fourth Ashes Test versus the Australians.
The pace bowler experienced discomfort in his left leg after the final ball in his spell during the morning session.
The touring camp stated the 27-year-old felt some "soreness" and required time off the field in order to be assessed "in the coming hours".
The series decider of the series beginning on 4 January starts at the end of the week.
England have already lost key quicks Mark Wood with a knee problem and another paceman because of a side injury during this series.
Matthew Fisher was added to the party as injury reinforcement.
His form was underwhelming early in the series, managing only three wickets.
He was dropped for the Adelaide match, then recalled for the Melbourne Test as Archer's replacement.
The county bowler performed better in the fourth Test, bagging two scalps with the ball, and scoring 28 runs with the bat among just a trio of teammates who passed ten runs.
Following a brief spell in Australia's second innings, he came back for the second day's play and had nightwatchman taken by the wicketkeeper.
Unfortunately, at the end of the fifth over, he bowled a change of pace to the batsman and promptly felt at his leg.
Gus Atkinson returned to the side for the Melbourne match after being left out the previous Test.
