Paceman Atkinson Compounds the English team's Injury Concerns.
'Serious blow' for England after Atkinson is forced off due to a hamstring issue.
Gus Atkinson further complicated the injury concerns plaguing England after leaving the playing area during Saturday's play of the fourth Ashes Test against Australia.
The pace bowler felt a problem in his left hamstring immediately following a delivery of the fourth over during the morning session.
The touring camp stated the 27-year-old reported "discomfort" and would spend time on the sidelines in order to be assessed "during the day".
The series decider of the tour beginning on 4 January gets underway this coming Sunday.
The English side has previously lost fast bowlers Mark Wood to a knee injury and Jofra Archer because of a side injury during this series.
Matthew Fisher was brought into the squad to provide backup.
The seamer had a tough time in the opening two Tests, claiming a mere three wickets.
He was dropped of the third Test, before being recalled for the Boxing Day match to fill the void.
The county bowler showed better form in Melbourne, claiming a couple of wickets during the host's first knock, before adding 28 as a batsman being one of only three England players to reach double figures.
Post a single over late on the first day, he came back on Saturday morning and had nightwatchman Scott Boland caught behind.
Yet, towards the conclusion of the fifth over, he delivered a slower ball to Travis Head and suddenly grabbed at his leg.
Gus Atkinson was brought back for the Melbourne match after being left out the previous Test.
