Seamer Atkinson Compounds England's Fitness Worries.
'Significant concern' for the English camp after Atkinson leaves the field due to a hamstring issue.
The English seamer added to England's injury problems when he left the ground early on day two in the Melbourne Test against Australia.
The right-arm seamer felt a problem in his left hamstring immediately following a delivery of the fourth over on Saturday.
The England team reported Atkinson felt some "soreness" and would spend time on the sidelines for further assessment "over the next few hours".
The final Test of the series at the SCG starts at the end of the week.
The visitors have previously lost key quicks one seamer to a knee injury and another paceman because of a side injury on this Ashes tour.
A replacement bowler was added to the party as injury reinforcement.
His form was underwhelming during the first two matches, managing only a handful of scalps.
He was omitted for the Adelaide match, then recalled for the fourth Test in the playing XI.
Surrey's Atkinson showed better form in Melbourne, bagging two scalps with the ball, and scoring 28 runs while batting as one of just three teammates to get into double digits.
Following a brief spell late on the first day, he returned the next day and had nightwatchman taken by the wicketkeeper.
Unfortunately, on the final ball of the fifth over, he delivered a change of pace to the batsman and suddenly grabbed for his hamstring.
Atkinson was brought back for the Boxing Day Test after being left out the Adelaide game.
