Paceman Atkinson Adds to the English team's Fitness Worries.
'Significant concern' for the touring side as Atkinson goes off with a hamstring injury.
Gus Atkinson increased the injury concerns plaguing England upon exiting the field on the second morning in the Melbourne Test in the Ashes series.
Atkinson felt a problem in his hamstring post-delivery in his spell at the MCG.
The England team indicated the 27-year-old reported "discomfort" and was to take time on the sidelines to undergo evaluation "in the coming hours".
The final Test in this Ashes battle beginning on 4 January begins on Sunday, 4 January.
England have already lost key quicks one seamer to a knee injury and Jofra Archer to a side strain during this series.
Matthew Fisher was added to the party as cover for Wood.
The seamer had a tough time during the first two matches, taking just three wickets.
He was left out from the previous Test, then recalled for the Boxing Day match to fill the void.
Surrey's Atkinson showed better form in Melbourne, bagging two scalps during the host's first knock, before adding 28 with the bat as one of just three teammates to get into double digits.
Post a single over late on the first day, he resumed on Saturday morning and dismissed the nightwatchman edging to the keeper.
Unfortunately, at the end of his spell, he delivered a variation to the batsman and suddenly grabbed his left hamstring.
The English bowler was recalled for the Boxing Day Test having missed the Adelaide game.
