Fast bowler Atkinson Adds to England's Injury Problems.
'Serious blow' for England as Atkinson is forced off due to a hamstring issue.
The English seamer increased the fitness woes of the England squad upon exiting the playing area early on day two in the Melbourne Test in the Ashes series.
Atkinson felt a problem in his left leg after the final ball in his spell at the MCG.
Team management reported the 27-year-old felt some "soreness" and would spend time away from the action to undergo evaluation "during the day".
The concluding match in this Ashes battle in Sydney begins at the end of the week.
England have previously lost key quicks Mark Wood with a knee problem and Jofra Archer because of a side injury on this Ashes tour.
A replacement bowler was added to the party as injury reinforcement.

He was left out of the third Test, before being recalled for the Melbourne Test in the playing XI.
Surrey's Atkinson performed better in the fourth Test, claiming a couple of wickets with the ball, then making 28 as a batsman as one of just three English batsmen to reach double figures.
Post a single over at the end of day one, he resumed the next day and removed Scott Boland Scott Boland caught behind.
However, towards the conclusion of that over, he sent down a change of pace to the batsman and promptly felt his left hamstring.
Atkinson was recalled for the Melbourne match having missed the previous Test.
