Fast bowler Atkinson Compounds the English team's Injury Concerns.
'Significant concern' for the touring side after Atkinson is forced off due to a hamstring issue.
The English seamer increased England's injury problems upon exiting the ground on the second morning of the Boxing Day Test versus the Australians.
The pace bowler pulled up with his left hamstring immediately following a delivery of the fourth over on Saturday.
The England team indicated the 27-year-old reported "discomfort" and was to take time away from the action to undergo evaluation "in the coming hours".
The final Test of the tour at the SCG gets underway at the end of the week.
England have previously lost fast bowlers one seamer to a knee injury and Jofra Archer because of a side injury during this series.
A replacement bowler was brought into the squad as cover for Wood.
Atkinson struggled during the first two matches, taking just a handful of scalps.
He was left out from the previous Test, before being recalled for the Boxing Day match as Archer's replacement.
The county bowler performed better in the fourth Test, bagging two scalps during the host's first knock, before adding 28 with the bat as one of just three teammates to reach double figures.
Post a single over at the end of day one, he came back the next day and dismissed the nightwatchman Scott Boland caught behind.
However, at the end of his spell, he bowled a variation to the batsman and immediately felt at his leg.
The English bowler returned to the side for the Boxing Day Test after being left out the Adelaide game.
