Fast bowler Gus Atkinson Compounds the English team's Injury Concerns.
'Major setback' for the English camp as Atkinson goes off with a hamstring injury.
The English seamer added to England's injury problems upon exiting the ground early on day two of the Boxing Day Test against Australia.
The right-arm seamer felt a problem in his left leg after the final ball in his spell during the morning session.
Team management indicated the 27-year-old reported "discomfort" and was to take time away from the action for further assessment "over the next few hours".
The final Test of the tour at the SCG starts this coming Sunday.
The visitors have previously lost fast bowlers one seamer to a knee injury and another paceman because of a side injury on this Ashes tour.
Matthew Fisher was added to the party to provide backup.
Atkinson struggled in the opening two Tests, claiming a mere three wickets.
He was omitted of the third Test, before being recalled for the Melbourne Test in the playing XI.
The county bowler performed better in the fourth Test, claiming a couple of wickets in Australia's first innings, then making 28 while batting being one of only three English batsmen who passed ten runs.
Following a brief spell in Australia's second innings, he returned for the second day's play and had nightwatchman edging to the keeper.
However, towards the conclusion of that over, he sent down a slower ball to the batsman and promptly felt at his leg.
Atkinson was brought back for the Melbourne match following his omission of the third.
