Seamer Atkinson Adds to the English team's Fitness Problems.
'Serious blow' for the touring side after Atkinson goes off due to a hamstring issue.
The English seamer added to the injury concerns plaguing England upon exiting the playing area on the second morning of the fourth Ashes Test against Australia.
Atkinson felt a problem in his left hamstring post-delivery that he bowled on Saturday.
The England team stated Atkinson reported "discomfort" and was to take time off the field in order to be assessed "in the coming hours".
The concluding match in this Ashes battle beginning on 4 January starts on Sunday, 4 January.
The English side has already lost key quicks Mark Wood with a knee problem and Jofra Archer with an abdominal strain on this Ashes tour.
A replacement bowler was brought into the squad as injury reinforcement.
The seamer had a tough time early in the series, claiming a mere three wickets.
He was omitted from the previous Test, then recalled for the Boxing Day match to fill the void.
Surrey's Atkinson showed better form in Melbourne, taking two wickets with the ball, and scoring 28 runs with the bat as one of just three English batsmen who passed ten runs.
After bowling one over in Australia's second innings, he resumed the next day and removed Scott Boland taken by the wicketkeeper.
Yet, on the final ball of his spell, he bowled a change of pace to the batsman and suddenly grabbed his left hamstring.
The English bowler was recalled for the Melbourne match having missed the Adelaide game.
