Fast bowler Atkinson Exacerbates England's Fitness Worries.
'Significant concern' for England as Atkinson goes off due to a hamstring issue.
The English seamer 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 pulled up with his left leg immediately following a delivery of the fourth over at the MCG.
Team management reported the 27-year-old reported "discomfort" and required time away from the action in order to be assessed "during the day".
The series decider of the series at the SCG begins on Sunday, 4 January.
England have been without strike bowlers one seamer to a knee injury and Jofra Archer to a side strain on this Ashes tour.
A replacement bowler was brought into the squad as cover for Wood.
Atkinson struggled early in the series, taking just three wickets.
He was dropped from the previous Test, then recalled for the fourth Test in the playing XI.
Atkinson improved at the MCG, bagging two scalps in Australia's first innings, and scoring 28 runs as a batsman among just a trio of English batsmen to reach double figures.
Following a brief spell at the end of day one, he resumed on Saturday morning and dismissed the nightwatchman taken by the wicketkeeper.
However, towards the conclusion of his spell, he delivered a slower ball to the batsman and suddenly grabbed for his hamstring.
Atkinson returned to the side for the Boxing Day Test after being left out of the third.
