Fast bowler Atkinson Compounds the English team's Injury Concerns.
'Serious blow' for the English camp as Atkinson is forced off with a hamstring injury.
The English seamer increased England's injury problems upon exiting the ground on the second morning in the Melbourne Test in the Ashes series.
Atkinson pulled up with his left hamstring post-delivery of the fourth over during the morning session.
The England team reported Atkinson reported "discomfort" and would spend time on the sidelines for further assessment "over the next few hours".
The final Test of the series at the SCG begins this coming Sunday.
England have been without strike bowlers one seamer to a knee injury and Jofra Archer with an abdominal strain on this Ashes tour.
Matthew Fisher was called up as cover for Wood.
Atkinson struggled in the opening two Tests, taking just a handful of scalps.
He was left out of the third Test, before being recalled for the Boxing Day match to fill the void.
Surrey's Atkinson showed better form in Melbourne, bagging two scalps in Australia's first innings, before adding 28 while batting as one of just three English batsmen to reach double figures.
Following a brief spell in Australia's second innings, he resumed for the second day's play and removed Scott Boland edging to the keeper.
Unfortunately, on the final ball of his spell, he delivered a variation to Travis Head and promptly felt for his hamstring.
Gus Atkinson was brought back for the fourth Ashes Test having missed the previous Test.
