Fast bowler Atkinson Adds to England's Fitness Problems.
'Significant concern' for England as Atkinson is forced off with a hamstring injury.
The English seamer further complicated the injury concerns plaguing England when he left the playing area on the second morning of the fourth Ashes Test in the Ashes series.
The pace bowler felt a problem in his left leg after the final ball that he bowled at the MCG.
Team management stated Atkinson reported "discomfort" and required time on the sidelines to undergo evaluation "in the coming hours".
The series decider of the series in Sydney begins this coming Sunday.
England have previously lost key quicks Mark Wood due to knee trouble and another paceman to a side strain on the current trip.
Matthew Fisher was added to the party as cover for Wood.
The seamer had a tough time early in the series, claiming a mere a handful of scalps.
He was left out for the Adelaide match, only to be brought back for the Boxing Day match to fill the void.
Atkinson performed better in the fourth Test, claiming a couple of wickets during the host's first knock, before adding 28 while batting being one of only three English batsmen to get into double digits.
Post a single over in Australia's second innings, he came back on Saturday morning and removed Scott Boland edging to the keeper.
Yet, on the final ball of the fifth over, he delivered a slower ball to Travis Head and promptly felt his left hamstring.
The English bowler returned to the side for the fourth Ashes Test having missed the previous Test.
