Seamer Atkinson Compounds the English team's Fitness Concerns.
'Major setback' for the touring side after Atkinson leaves the field suffering a hamstring problem.
Gus Atkinson increased the injury concerns plaguing England when he left the field during Saturday's play of the Boxing Day Test in the Ashes series.
The right-arm seamer felt a problem in his left hamstring post-delivery of the fourth over at the MCG.
Team management reported the 27-year-old had experienced "tightness" and was to take time away from the action for further assessment "in the coming hours".
The final Test of the series beginning on 4 January gets underway on Sunday, 4 January.
England have been without strike bowlers one seamer to a knee injury and Jofra Archer to a side strain on the current trip.
Matthew Fisher was called up to provide backup.
The seamer had a tough time in the opening two Tests, claiming a mere a handful of scalps.
He was dropped for the Adelaide match, before being recalled for the Melbourne Test in the playing XI.
Surrey's Atkinson showed better form in Melbourne, bagging two scalps during the host's first knock, before adding 28 with the bat among just a trio of England players who passed ten runs.
Post a single over in Australia's second innings, he came back the next day and dismissed the nightwatchman taken by the wicketkeeper.
Unfortunately, on the final ball of the fifth over, he sent down a variation to Travis Head and suddenly grabbed his left hamstring.
The English bowler was recalled for the fourth Ashes Test having missed of the third.
