Seamer Atkinson Compounds the English team's Injury Problems.
'Serious blow' for the touring side as Atkinson leaves the field suffering a hamstring problem.
Gus Atkinson added to the fitness woes of the England squad upon exiting the ground early on day two of the Boxing Day Test in the Ashes series.
The right-arm seamer experienced discomfort in his left leg after the final ball that he bowled on Saturday.
The touring camp reported Atkinson reported "discomfort" and required time on the sidelines in order to be assessed "over the next few hours".
The concluding match of the series at the SCG gets underway on Sunday, 4 January.
England have been without strike bowlers one seamer due to knee trouble and Jofra Archer with an abdominal strain on this Ashes tour.
Matthew Fisher was added to the party as cover for Wood.
The seamer had a tough time early in the series, claiming a mere three wickets.
He was omitted from the previous Test, then recalled for the Melbourne Test to fill the void.
Surrey's Atkinson improved at the MCG, bagging two scalps with the ball, before adding 28 while batting as one of just three England players to get into double digits.
Post a single over late on the first day, he came back for the second day's play and had nightwatchman edging to the keeper.
Unfortunately, at the end of his spell, he bowled a variation to Travis Head and suddenly grabbed his left hamstring.
The English bowler returned to the side for the Melbourne match having missed of the third.
