Seamer Atkinson Adds to the English team's Fitness Worries.
'Major setback' for England after Atkinson goes off with a hamstring injury.
The pace bowler added to the injury concerns plaguing England upon exiting the field on the second morning in the Melbourne Test in the Ashes series.
The pace bowler felt a problem in his hamstring after the final ball that he bowled at the MCG.
The touring camp reported Atkinson reported "discomfort" and was to take time away from the action for further assessment "during the day".
The final Test in this Ashes battle in Sydney begins this coming Sunday.
The visitors have previously lost key quicks one seamer with a knee problem and another paceman with an abdominal strain during this series.
Matthew Fisher was called up as cover for Wood.
Atkinson struggled in the opening two Tests, taking just three wickets.
He was dropped of the third Test, before being recalled for the Melbourne Test in the playing XI.
Surrey's Atkinson showed better form in Melbourne, taking two wickets in Australia's first innings, before adding 28 with the bat as one of just three English batsmen who passed ten runs.
After bowling one over at the end of day one, he returned for the second day's play and had nightwatchman edging to the keeper.
Unfortunately, at the end of his spell, he sent down a slower ball to Travis Head and suddenly grabbed for his hamstring.
Atkinson returned to the side for the Melbourne match having missed the Adelaide game.
