Fast bowler Gus Atkinson Adds to the English team's Injury Worries.
'Major setback' for the English camp after Atkinson leaves the field suffering a hamstring problem.
The pace bowler added to England's injury problems when he left the playing area during Saturday's play of the fourth Ashes Test versus the Australians.
The pace bowler felt a problem in his hamstring post-delivery of the fourth over on Saturday.
Team management indicated the 27-year-old had experienced "tightness" and would spend time on the sidelines in order to be assessed "during the day".
The concluding match of the series at the SCG begins on Sunday, 4 January.
The English side has already lost strike bowlers Mark Wood due to knee trouble and another paceman with an abdominal strain on this Ashes tour.
A replacement bowler was brought into the squad to provide backup.
Atkinson struggled in the opening two Tests, claiming a mere a handful of scalps.
He was omitted of the third Test, before being recalled for the fourth Test in the playing XI.
Surrey's Atkinson improved at the MCG, taking two wickets with the ball, then making 28 while batting among just a trio of England players to get into double digits.
Following a brief spell in Australia's second innings, he resumed for the second day's play and had nightwatchman edging to the keeper.
Yet, towards the conclusion of the fifth over, he sent down a slower ball to Travis Head and promptly felt his left hamstring.
Atkinson was recalled for the Melbourne match after being left out the previous Test.
