'Major setback' for England after Atkinson is forced off due to a hamstring issue.
Gus Atkinson added to England's injury problems upon exiting the field early on day two in the Melbourne Test against Australia.
The right-arm seamer felt a problem in his hamstring post-delivery in his spell on Saturday.
The touring camp reported the 27-year-old had experienced "tightness" and required time away from the action to undergo evaluation "during the day".
The series decider in this Ashes battle in Sydney gets underway this coming Sunday.
The visitors have already lost fast bowlers Mark Wood due to knee trouble and Jofra Archer with an abdominal strain on this Ashes tour.
Matthew Fisher was added to the party to provide backup.
The seamer had a tough time during the first two matches, claiming a mere three wickets.
He was left out for the Adelaide match, then recalled for the Melbourne Test to fill the void.
Surrey's Atkinson performed better in the fourth Test, claiming a couple of wickets during the host's first knock, before adding 28 as a batsman as one of just three English batsmen to reach double figures.
Following a brief spell late on the first day, he came back for the second day's play and dismissed the nightwatchman taken by the wicketkeeper.
However, towards the conclusion of that over, he delivered a change of pace to the batsman and suddenly grabbed his left hamstring.
The English bowler returned to the side for the Boxing Day Test after being left out the previous Test.
