Seamer Atkinson Compounds the English team's Injury Worries.
'Significant concern' for the English camp after Atkinson leaves the field due to a hamstring issue.
The pace bowler increased England's injury problems after leaving the playing area on the second morning of the Boxing Day Test in the Ashes series.
The right-arm seamer felt a problem in his left hamstring immediately following a delivery of the fourth over at the MCG.
Team management indicated the 27-year-old felt some "soreness" and was to take time off the field for further assessment "in the coming hours".
The final Test in this Ashes battle beginning on 4 January gets underway on Sunday, 4 January.
England have previously lost key quicks one seamer due to knee trouble and another paceman with an abdominal strain during this series.
A replacement bowler was brought into the squad as cover for Wood.
The seamer had a tough time in the opening two Tests, managing only three wickets.
He was dropped for the Adelaide match, before being recalled for the Melbourne Test to fill the void.
Atkinson showed better form in Melbourne, taking two wickets with the ball, then making 28 while batting as one of just three teammates to get into double digits.
After bowling one over late on the first day, he resumed on Saturday morning and dismissed the nightwatchman edging to the keeper.
Yet, at the end of the fifth over, he sent down a variation to Travis Head and promptly felt at his leg.
Atkinson was brought back for the fourth Ashes Test having missed of the third.
