Fast bowler Atkinson Exacerbates the English team's Injury Problems.
'Major setback' for the English camp after Atkinson is forced off due to a hamstring issue.
The pace bowler added to the fitness woes of the England squad upon exiting the field during Saturday's play of the Boxing Day Test against Australia.
The pace bowler experienced discomfort in his left leg post-delivery in his spell on Saturday.
The touring camp stated the 27-year-old had experienced "tightness" and required time on the sidelines to undergo evaluation "in the coming hours".
The concluding match of the series at the SCG begins on Sunday, 4 January.
The visitors have already lost strike bowlers one seamer due to knee trouble and another paceman with an abdominal strain on the current trip.
A replacement bowler was added to the party to provide backup.
His form was underwhelming during the first two matches, claiming a mere three wickets.
He was left out of the third Test, only to be brought back for the Melbourne Test as Archer's replacement.
The county bowler improved at the MCG, bagging two scalps with the ball, before adding 28 as a batsman being one of only three England players to get into double digits.
After bowling one over late on the first day, he returned for the second day's play and dismissed the nightwatchman taken by the wicketkeeper.
Unfortunately, towards the conclusion of that over, he delivered a slower ball to Travis Head and immediately felt at his leg.
Gus Atkinson was recalled for the fourth Ashes Test having missed the previous Test.
