Fast bowler Atkinson Adds to the English team's Injury Worries.
'Major setback' for England as Atkinson leaves the field suffering a hamstring problem.
The English seamer increased England's injury problems when he left the ground early on day two in the Melbourne Test in the Ashes series.
The right-arm seamer felt a problem in his hamstring after the final ball of the fourth over at the MCG.
The England team indicated the 27-year-old felt some "soreness" and was to take time on the sidelines to undergo evaluation "in the coming hours".
The final Test of the tour at the SCG gets underway at the end of the week.
England have been without key quicks Mark Wood due to knee trouble and Jofra Archer with an abdominal strain on this Ashes tour.
Matthew Fisher was brought into the squad as cover for Wood.
Atkinson struggled early in the series, managing only a handful of scalps.
He was omitted from the previous Test, before being recalled for the Melbourne Test to fill the void.
Surrey's Atkinson performed better in the fourth Test, taking two wickets during the host's first knock, before adding 28 while batting being one of only three English batsmen to get into double digits.
Following a brief spell late on the first day, he resumed on Saturday morning and removed Scott Boland taken by the wicketkeeper.
However, on the final ball of his spell, he bowled a change of pace to Travis Head and immediately felt his left hamstring.
The English bowler returned to the side for the Melbourne match following his omission the previous Test.
