Paceman Atkinson Exacerbates England's Fitness Problems.
'Major setback' for the touring side as Atkinson leaves the field due to a hamstring issue.
The English seamer further complicated the fitness woes of the England squad when he left the field during Saturday's play of the Boxing Day Test versus the Australians.
The right-arm seamer experienced discomfort in his left leg after the final ball that he bowled on Saturday.
The England team stated the 27-year-old felt some "soreness" and was to take time off the field for further assessment "over the next few hours".
The series decider in this Ashes battle at the SCG begins on Sunday, 4 January.
England have already lost key quicks Mark Wood with a knee problem and Jofra Archer with an abdominal strain on the current trip.
A replacement bowler was called up as cover for Wood.
His form was underwhelming during the first two matches, managing only three wickets.
He was omitted for the Adelaide match, then recalled for the Melbourne Test as Archer's replacement.
Atkinson performed better in the fourth Test, bagging two scalps with the ball, and scoring 28 runs while batting being one of only three English batsmen to reach double figures.
After bowling one over late on the first day, he came back for the second day's play and removed Scott Boland edging to the keeper.
Yet, on the final ball of the fifth over, he sent down a slower ball to Travis Head and immediately felt for his hamstring.
The English bowler returned to the side for the Boxing Day Test having missed of the third.
