Paceman Atkinson Compounds England's Fitness Problems.
'Serious blow' for the touring side as Atkinson goes off due to a hamstring issue.
The pace bowler added to England's injury problems upon exiting the field on the second morning of the fourth Ashes Test in the Ashes series.
The right-arm seamer felt a problem in his left hamstring post-delivery in his spell at the MCG.
Team management stated the 27-year-old reported "discomfort" and would spend time away from the action for further assessment "in the coming hours".
The final Test in this Ashes battle beginning on 4 January gets underway at the end of the week.
England have been without strike bowlers Mark Wood due to knee trouble and another paceman with an abdominal strain on the current trip.
A replacement bowler was added to the party as injury reinforcement.
The seamer had a tough time during the first two matches, managing only a handful of scalps.
He was dropped for the Adelaide match, only to be brought back for the fourth Test to fill the void.
Atkinson performed better in the fourth Test, taking two wickets with the ball, and scoring 28 runs while batting as one of just three England players to get into double digits.
Post a single over in Australia's second innings, he resumed for the second day's play and dismissed the nightwatchman taken by the wicketkeeper.
However, at the end of his spell, he bowled a slower ball to Travis Head and immediately felt at his leg.
Atkinson returned to the side for the Melbourne match after being left out the previous Test.
