Seamer Gus Atkinson Exacerbates the English team's Fitness Concerns.
'Significant concern' for the touring side as Atkinson goes off due to a hamstring issue.
The English seamer further complicated the injury concerns plaguing England after leaving the ground early on day two of the fourth Ashes Test in the Ashes series.
Atkinson felt a problem in his hamstring post-delivery in his spell at the MCG.
The England team indicated Atkinson had experienced "tightness" and was to take time away from the action for further assessment "in the coming hours".
The series decider in this Ashes battle beginning on 4 January starts at the end of the week.
England have previously lost key quicks one seamer due to knee trouble and Jofra Archer because of a side injury on the current trip.
Matthew Fisher was brought into the squad to provide backup.
Atkinson struggled in the opening two Tests, managing only a handful of scalps.
He was dropped from the previous Test, before being recalled for the Boxing Day match in the playing XI.
Atkinson showed better form in Melbourne, claiming a couple of wickets in Australia's first innings, and scoring 28 runs as a batsman as one of just three teammates who passed ten runs.
Post a single over late on the first day, he returned on Saturday morning and had nightwatchman edging to the keeper.
However, towards the conclusion of that over, he sent down a change of pace to Travis Head and immediately felt for his hamstring.
Atkinson was recalled for the fourth Ashes Test having missed of the third.
