Fast bowler Atkinson Adds to England's Injury Worries.
'Significant concern' for England after Atkinson is forced off due to a hamstring issue.
The pace bowler increased England's injury problems upon exiting the field during Saturday's play in the Melbourne Test against Australia.

The England team indicated the 27-year-old had experienced "tightness" and was to take time off the field for further assessment "during the day".
The series decider of the tour in Sydney begins this coming Sunday.
England have previously lost strike bowlers one seamer to a knee injury and another paceman to a side strain during this series.
Matthew Fisher was added to the party to provide backup.
The seamer had a tough time during the first two matches, managing only three wickets.
He was omitted for the Adelaide match, before being recalled for the Melbourne Test as Archer's replacement.
Atkinson performed better in the fourth Test, claiming a couple of wickets during the host's first knock, before adding 28 while batting being one of only three England players to get into double digits.
Post a single over late on the first day, he resumed on Saturday morning and removed Scott Boland Scott Boland caught behind.
Yet, on the final ball of that over, he delivered a variation to the batsman and suddenly grabbed for his hamstring.
Gus Atkinson returned to the side for the Melbourne match having missed the Adelaide game.
