Paceman Atkinson Compounds England's Injury Worries.
'Major setback' for the English camp as Atkinson leaves the field suffering a hamstring problem.
Gus Atkinson increased England's injury problems after leaving the playing area on the second morning of the Boxing Day Test versus the Australians.
The pace bowler felt a problem in his hamstring after the final ball in his spell at the MCG.
The touring camp indicated the 27-year-old reported "discomfort" and required time away from the action for further assessment "in the coming hours".
The final Test of the series at the SCG gets underway this coming Sunday.
England have been without strike bowlers one seamer with a knee problem and another paceman with an abdominal strain on this Ashes tour.
A replacement bowler was called up as cover for Wood.
The seamer had a tough time in the opening two Tests, managing only a handful of scalps.
He was dropped from the previous Test, only to be brought back for the Boxing Day match as Archer's replacement.
Surrey's Atkinson performed better in the fourth Test, taking two wickets during the host's first knock, and scoring 28 runs with the bat among just a trio of England players who passed ten runs.
After bowling one over late on the first day, he resumed the next day and removed Scott Boland taken by the wicketkeeper.
Unfortunately, on the final ball of that over, he delivered a slower ball to the batsman and immediately felt his left hamstring.
Gus Atkinson returned to the side for the Boxing Day Test following his omission of the third.
