Paceman Atkinson Compounds England's Fitness Problems.
'Significant concern' for the touring side after Atkinson is forced off due to a hamstring issue.
The English seamer added to the injury concerns plaguing England after leaving the field on the second morning of the Boxing Day Test against Australia.
The right-arm seamer experienced discomfort in his hamstring post-delivery of the fourth over during the morning session.
Team management indicated Atkinson had experienced "tightness" and required time off the field for further assessment "during the day".
The concluding match of the series beginning on 4 January gets underway this coming Sunday.
The English side has previously lost key quicks Mark Wood with a knee problem 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, managing only three wickets.
He was dropped for the Adelaide match, only to be brought back for the fourth Test in the playing XI.
Surrey's Atkinson improved at the MCG, taking two wickets during the host's first knock, and scoring 28 runs as a batsman among just a trio of teammates who passed ten runs.
After bowling one over in Australia's second innings, he came back the next day and had nightwatchman taken by the wicketkeeper.
However, at the end of his spell, he sent down a variation to Travis Head and suddenly grabbed for his hamstring.
Atkinson was recalled for the Boxing Day Test following his omission of the third.
