Fast bowler Atkinson Exacerbates the English team's Injury Concerns.
'Serious blow' for the touring side after Atkinson is forced off with a hamstring injury.
The pace bowler further complicated the fitness woes of the England squad after leaving the field during Saturday's play of the fourth Ashes Test against Australia.
The pace bowler felt a problem in his hamstring after the final ball that he bowled during the morning session.
The touring camp stated the 27-year-old felt some "soreness" and required time away from the action in order to be assessed "over the next few hours".
The concluding match of the series at the SCG gets underway on Sunday, 4 January.
England have already lost fast bowlers Mark Wood with a knee problem and another paceman with an abdominal strain on the current trip.
Matthew Fisher was called up as cover for Wood.
The seamer had a tough time during the first two matches, managing only three wickets.
He was omitted from the previous Test, only to be brought back for the Melbourne Test to fill the void.
Atkinson improved at the MCG, bagging two scalps during the host's first knock, then making 28 as a batsman as one of just three England players to reach double figures.
Following a brief spell in Australia's second innings, he resumed the next day and dismissed the nightwatchman Scott Boland caught behind.
Unfortunately, at the end of the fifth over, he sent down a slower ball to Travis Head and suddenly grabbed at his leg.
The English bowler was brought back for the fourth Ashes Test after being left out the Adelaide game.
