Seamer Gus Atkinson Adds to the English team's Fitness Worries.
'Significant concern' for England after Atkinson leaves the field suffering a hamstring problem.
The pace bowler added to the fitness woes of the England squad when he left the field on the second morning of the fourth Ashes Test versus the Australians.
The right-arm seamer experienced discomfort in his left leg after the final ball of the fourth over during the morning session.
Team management reported Atkinson had experienced "tightness" and was to take time away from the action in order to be assessed "during the day".
The final Test in this Ashes battle at the SCG begins at the end of the week.
England have previously lost fast bowlers Mark Wood to a knee injury 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, claiming a mere three wickets.
He was dropped for the Adelaide match, then recalled for the Boxing Day match in the playing XI.
Atkinson performed better in the fourth Test, bagging two scalps with the ball, before adding 28 as a batsman as one of just three England players who passed ten runs.
Post a single over at the end of day one, he came back for the second day's play and had nightwatchman Scott Boland caught behind.
Unfortunately, on the final ball of that over, he bowled a variation to the batsman and suddenly grabbed his left hamstring.
The English bowler returned to the side for the Melbourne match after being left out the Adelaide game.
