Seamer Gus Atkinson Adds to England's Fitness Worries.
'Major setback' for the English camp as Atkinson goes off with a hamstring injury.
The pace bowler increased the fitness woes of the England squad after leaving the field on the second morning of the Boxing Day Test versus the Australians.
The right-arm seamer felt a problem in his left hamstring post-delivery of the fourth over at the MCG.
The England team reported Atkinson had experienced "tightness" and would spend time away from the action in order to be assessed "over the next few hours".
The series decider in this Ashes battle at the SCG starts this coming Sunday.
The English side has been without fast bowlers one seamer to a knee injury and another paceman because of a side injury during this series.
Matthew Fisher was brought into the squad as cover for Wood.
The seamer had a tough time during the first two matches, claiming a mere three wickets.
He was dropped of the third Test, then recalled for the fourth Test in the playing XI.
Surrey's Atkinson showed better form in Melbourne, taking two wickets with the ball, and scoring 28 runs as a batsman as one of just three teammates to reach double figures.
Following a brief spell in Australia's second innings, he resumed on Saturday morning and removed Scott Boland taken by the wicketkeeper.
Unfortunately, on the final ball of that over, he delivered a change of pace to the batsman and immediately felt his left hamstring.
Atkinson was brought back for the Melbourne match having missed the previous Test.
