Fast bowler Gus Atkinson Adds to the English team's Fitness Worries.
'Serious blow' for the English camp after Atkinson is forced off due to a hamstring issue.
The English seamer added to England's injury problems after leaving the field on the second morning in the Melbourne Test versus the Australians.
Atkinson experienced discomfort in his left hamstring immediately following a delivery of the fourth over during the morning session.
The touring camp indicated Atkinson reported "discomfort" and required time away from the action to undergo evaluation "in the coming hours".
The concluding match of the series at the SCG begins this coming Sunday.
The visitors have been without strike bowlers Mark Wood with a knee problem and Jofra Archer with an abdominal strain on the current trip.
A replacement bowler was brought into the squad to provide backup.
His form was underwhelming during the first two matches, managing only a handful of scalps.
He was left out of the third Test, then recalled for the Melbourne Test in the playing XI.
Surrey's Atkinson improved at the MCG, claiming a couple of wickets with the ball, before adding 28 while batting being one of only three English batsmen to get into double digits.
After bowling one over in Australia's second innings, he came back the next day and dismissed the nightwatchman edging to the keeper.
Yet, on the final ball of the fifth over, he delivered a slower ball to Travis Head and suddenly grabbed his left hamstring.
Gus Atkinson was recalled for the Melbourne match having missed the previous Test.
