Paceman Atkinson Adds to the English team's Injury Concerns.
'Serious blow' for England as Atkinson leaves the field suffering a hamstring problem.
The pace bowler added to England's injury problems upon exiting the field early on day two of the Boxing Day Test against Australia.
Atkinson felt a problem in his left hamstring after the final ball in his spell during the morning session.
Team management indicated the 27-year-old felt some "soreness" and was to take time off the field to undergo evaluation "over the next few hours".
The series decider in this Ashes battle in Sydney begins this coming Sunday.
The visitors have been without strike bowlers Mark Wood to a knee injury and Jofra Archer to a side strain during this series.
A replacement bowler was called up as injury reinforcement.
Atkinson struggled in the opening two Tests, managing only three wickets.
He was dropped for the Adelaide match, then recalled for the Melbourne Test to fill the void.
Surrey's Atkinson showed better form in Melbourne, claiming a couple of wickets in Australia's first innings, then making 28 with the bat as one of just three English batsmen to get into double digits.
After bowling one over in Australia's second innings, he resumed the next day and had nightwatchman edging to the keeper.
Unfortunately, at the end of his spell, he bowled a change of pace to the batsman and suddenly grabbed at his leg.
The English bowler was recalled for the fourth Ashes Test following his omission of the third.
