Fast bowler Gus Atkinson Exacerbates the English team's Fitness Problems.
'Major setback' for England as Atkinson goes off with a hamstring injury.
The pace bowler further complicated the injury concerns plaguing England when he left the field during Saturday's play in the Melbourne Test in the Ashes series.
The pace bowler pulled up with his left hamstring immediately following a delivery of the fourth over at the MCG.
The England team reported the 27-year-old had experienced "tightness" and was to take time off the field for further assessment "during the day".
The concluding match of the tour at the SCG gets underway this coming Sunday.
The visitors have already lost strike bowlers one seamer due to knee trouble and Jofra Archer to a side strain on the current trip.
Matthew Fisher was called up as injury reinforcement.
The seamer had a tough time early in the series, managing only a handful of scalps.
He was omitted of the third Test, only to be brought back for the Melbourne Test in the playing XI.
Surrey's Atkinson showed better form in Melbourne, bagging two scalps in Australia's first innings, then making 28 with the bat among just a trio of English batsmen to reach double figures.
After bowling one over late on the first day, he came back on Saturday morning and removed Scott Boland Scott Boland caught behind.
Yet, on the final ball of that over, he sent down a slower ball to Travis Head and suddenly grabbed for his hamstring.
Atkinson was brought back for the Boxing Day Test having missed of the third.
