Seamer Atkinson Compounds England's Fitness Problems.
'Major setback' for the English camp after Atkinson goes off due to a hamstring issue.
Gus Atkinson further complicated England's injury problems upon exiting the ground during Saturday's play in the Melbourne Test versus the Australians.
The pace bowler experienced discomfort in his hamstring post-delivery of the fourth over at the MCG.
The England team stated Atkinson reported "discomfort" and would spend time away from the action to undergo evaluation "over the next few hours".
The series decider of the tour at the SCG begins this coming Sunday.
England have already lost fast bowlers one seamer due to knee trouble and another paceman with an abdominal strain on this Ashes tour.
A replacement bowler was brought into the squad as cover for Wood.
Atkinson struggled early in the series, claiming a mere three wickets.
He was left out of the third Test, only to be brought back for the Boxing Day match in the playing XI.
Surrey's Atkinson improved at the MCG, taking two wickets during the host's first knock, before adding 28 with the bat being one of only three English batsmen to get into double digits.
Post a single over late on the first day, he came back the next day and dismissed the nightwatchman edging to the keeper.
However, at the end of his spell, he bowled a slower ball to the batsman and suddenly grabbed his left hamstring.
Atkinson was recalled for the Boxing Day Test having missed of the third.
