Fast bowler Gus Atkinson Compounds England's Injury Worries.
'Significant concern' for the English camp after Atkinson is forced off with a hamstring injury.
The English seamer increased England's injury problems upon exiting the ground on the second morning of the fourth Ashes Test versus the Australians.
The pace bowler experienced discomfort in his left leg after the final ball in his spell at the MCG.
Team management stated the 27-year-old had experienced "tightness" and would spend time on the sidelines for further assessment "over the next few hours".
The series decider of the series beginning on 4 January starts on Sunday, 4 January.
The visitors have already lost key quicks Mark Wood due to knee trouble and another paceman to a side strain on this Ashes tour.
Matthew Fisher was added to the party as cover for Wood.
Atkinson struggled early in the series, managing only three wickets.
He was dropped from the previous Test, then recalled for the fourth Test as Archer's replacement.
Atkinson showed better form in Melbourne, claiming a couple of wickets in Australia's first innings, before adding 28 as a batsman as one of just three teammates to get into double digits.
After bowling one over late on the first day, he returned for the second day's play and had nightwatchman edging to the keeper.
However, on the final ball of that over, he sent down a change of pace to Travis Head and promptly felt at his leg.
Gus Atkinson was recalled for the Boxing Day Test after being left out the previous Test.
