Paceman Atkinson Compounds England's Injury Problems.
'Serious blow' for the English camp after Atkinson leaves the field suffering a hamstring problem.
The English seamer further complicated the fitness woes of the England squad upon exiting the ground on the second morning of the fourth Ashes Test in the Ashes series.
The pace bowler pulled up with his hamstring post-delivery in his spell on Saturday.
Team management reported the 27-year-old felt some "soreness" and would spend time off the field for further assessment "during the day".
The concluding match of the series at the SCG begins on Sunday, 4 January.
The English side has previously lost key quicks Mark Wood with a knee problem and another paceman with an abdominal strain during this series.
Matthew Fisher was added to the party as cover for Wood.
Atkinson struggled early in the series, claiming a mere 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, bagging two scalps during the host's first knock, and scoring 28 runs while batting being one of only three English batsmen to reach double figures.
Following a brief spell at the end of day one, he came back for the second day's play and had nightwatchman taken by the wicketkeeper.
Unfortunately, towards the conclusion of the fifth over, he bowled a change of pace to Travis Head and promptly felt for his hamstring.
Gus Atkinson was recalled for the Boxing Day Test having missed the Adelaide game.
