Fast bowler Gus Atkinson Adds to England's Fitness Problems.
'Significant concern' for England after Atkinson is forced off due to a hamstring issue.
The English seamer further complicated England's injury problems when he left the playing area on the second morning in the Melbourne Test versus the Australians.
The right-arm seamer pulled up with his left hamstring immediately following a delivery in his spell at the MCG.
The England team stated the 27-year-old felt some "soreness" and was to take time off the field in order to be assessed "during the day".
The final Test of the series at the SCG begins this coming Sunday.
The visitors have been without key quicks Mark Wood with a knee problem and another paceman to a side strain during this series.
A replacement bowler was called up as cover for Wood.
His form was underwhelming during the first two matches, 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.
Atkinson improved at the MCG, taking two wickets in Australia's first innings, then making 28 with the bat as one of just three English batsmen who passed ten runs.
After bowling one over at the end of day one, he resumed the next day and removed Scott Boland Scott Boland caught behind.
However, on the final ball of his spell, he delivered a variation to Travis Head and promptly felt at his leg.
Gus Atkinson returned to the side for the fourth Ashes Test after being left out the previous Test.
