Seamer Atkinson Compounds England's Fitness Concerns.
'Major setback' for the English camp as Atkinson leaves the field due to a hamstring issue.
The English seamer added to the injury concerns plaguing England upon exiting the ground during Saturday's play of the fourth Ashes Test in the Ashes series.
The right-arm seamer felt a problem in his left leg after the final ball of the fourth over on Saturday.
Team management indicated the 27-year-old felt some "soreness" and was to take time on the sidelines to undergo evaluation "in the coming hours".
The series decider of the series beginning on 4 January starts on Sunday, 4 January.
The visitors have already lost fast bowlers Mark Wood due to knee trouble and Jofra Archer to a side strain on the current trip.
Matthew Fisher was called up as injury reinforcement.
Atkinson struggled during the first two matches, taking just a handful of scalps.
He was omitted from the previous Test, before being recalled for the Boxing Day match in the playing XI.
The county bowler showed better form in Melbourne, taking two wickets with the ball, then making 28 as a batsman being one of only three England players to get into double digits.
Post a single over late on the first day, he resumed the next day and had nightwatchman Scott Boland caught behind.
Unfortunately, towards the conclusion of his spell, he delivered a variation to Travis Head and promptly felt his left hamstring.
Gus Atkinson was recalled for the fourth Ashes Test after being left out the previous Test.
