Fast bowler Atkinson Exacerbates the English team's Fitness Concerns.
'Serious blow' for the English camp after Atkinson leaves the field with a hamstring injury.
The English seamer increased the fitness woes of the England squad after leaving the ground early on day two of the Boxing Day Test versus the Australians.
The pace bowler felt a problem in his left leg post-delivery of the fourth over at the MCG.
The touring camp reported Atkinson felt some "soreness" and would spend time off the field in order to be assessed "over the next few hours".
The concluding match in this Ashes battle in Sydney starts this coming Sunday.
The visitors have already lost key quicks one seamer to a knee injury and Jofra Archer to a side strain on this Ashes tour.
Matthew Fisher was called up as cover for Wood.
His form was underwhelming in the opening two Tests, managing only three wickets.
He was left out from the previous Test, then recalled for the fourth Test as Archer's replacement.
Atkinson improved at the MCG, bagging two scalps with the ball, before adding 28 with the bat being one of only three teammates to get into double digits.
Following a brief spell in Australia's second innings, he came back the next day and removed Scott Boland edging to the keeper.
Yet, towards the conclusion of the fifth over, he bowled a change of pace to Travis Head and suddenly grabbed for his hamstring.
Gus Atkinson was brought back for the Melbourne match having missed the Adelaide game.
