Fast bowler Gus Atkinson Adds to England's Fitness Concerns.
'Major setback' for the touring side as Atkinson leaves the field suffering a hamstring problem.
The English seamer further complicated England's injury problems upon exiting the playing area during Saturday's play in the Melbourne Test against Australia.
The pace bowler felt a problem in his hamstring after the final ball that he bowled on Saturday.
The England team indicated Atkinson felt some "soreness" and was to take time on the sidelines for further assessment "in the coming hours".
The series decider in this Ashes battle in Sydney gets underway on Sunday, 4 January.
The English side has been without fast bowlers one seamer with a knee problem and Jofra Archer because of a side injury on the current trip.
A replacement bowler was added to the party to provide backup.
His form was underwhelming early in the series, taking just a handful of scalps.
He was left out from the previous Test, only to be brought back for the Boxing Day match as Archer's replacement.
The county bowler improved at the MCG, taking two wickets in Australia's first innings, and scoring 28 runs with the bat as one of just three England players to reach double figures.
After bowling one over in Australia's second innings, he resumed the next day and removed Scott Boland Scott Boland caught behind.
Yet, on the final ball of that over, he delivered a slower ball to the batsman and suddenly grabbed at his leg.
Atkinson was recalled for the Melbourne match following his omission of the third.
