Paceman Gus Atkinson Compounds the English team's Fitness Worries.
'Significant concern' for the touring side after Atkinson leaves the field due to a hamstring issue.
The pace bowler added to the fitness woes of the England squad after leaving the ground during Saturday's play in the Melbourne Test in the Ashes series.
Atkinson experienced discomfort in his left leg after the final ball that he bowled on Saturday.
The England team indicated the 27-year-old felt some "soreness" and required time off the field in order to be assessed "during the day".
The series decider in this Ashes battle at the SCG starts this coming Sunday.
England have been without fast bowlers Mark Wood due to knee trouble and Jofra Archer to a side strain on this Ashes tour.
Matthew Fisher was brought into the squad as injury reinforcement.
His form was underwhelming early in the series, claiming a mere a handful of scalps.
He was dropped of the third Test, then recalled for the Melbourne Test in the playing XI.
The county bowler improved at the MCG, bagging two scalps in Australia's first innings, before adding 28 while batting as one of just three English batsmen to reach double figures.
Post a single over in Australia's second innings, he came back for the second day's play and had nightwatchman Scott Boland caught behind.
Unfortunately, at the end of the fifth over, he sent down a change of pace to Travis Head and suddenly grabbed his left hamstring.
The English bowler was recalled for the Melbourne match having missed the previous Test.
