Fast bowler Atkinson Compounds the English team's Fitness Concerns.
'Major setback' for England after Atkinson goes off with a hamstring injury.
Gus Atkinson increased the injury concerns plaguing England when he left the field early on day two in the Melbourne Test versus the Australians.
The right-arm seamer experienced discomfort in his left hamstring post-delivery that he bowled at the MCG.
The England team stated Atkinson felt some "soreness" and required time away from the action to undergo evaluation "over the next few hours".
The series decider of the tour at the SCG begins this coming Sunday.
England have previously lost fast bowlers Mark Wood due to knee trouble and another paceman because of a side injury on the current trip.
Matthew Fisher was brought into the squad to provide backup.
The seamer had a tough time in the opening two Tests, managing only three wickets.
He was omitted of the third Test, then recalled for the fourth Test as Archer's replacement.
The county bowler showed better form in Melbourne, claiming a couple of wickets during the host's first knock, before adding 28 while batting as one of just three English batsmen who passed ten runs.
Post a single over late on the first day, he returned for the second day's play and dismissed the nightwatchman edging to the keeper.
Yet, towards the conclusion of his spell, he bowled a variation to the batsman and immediately felt his left hamstring.
The English bowler returned to the side for the Boxing Day Test following his omission of the third.
