Fast bowler Gus Atkinson Adds to England's Fitness Concerns.
'Significant concern' for the English camp after Atkinson goes off suffering a hamstring problem.
The pace bowler added to the fitness woes of the England squad after leaving the playing area on the second morning of the Boxing Day Test against Australia.
The right-arm seamer felt a problem in his left leg after the final ball in his spell on Saturday.
The touring camp reported Atkinson felt some "soreness" and required time off the field to undergo evaluation "over the next few hours".
The concluding match of the tour in Sydney starts this coming Sunday.
England have been without key quicks one seamer due to knee trouble and Jofra Archer with an abdominal strain on this Ashes tour.
A replacement bowler was brought into the squad as injury reinforcement.
His form was underwhelming during the first two matches, managing only a handful of scalps.
He was left out from the previous Test, only to be brought back for the fourth Test as Archer's replacement.
Surrey's Atkinson performed better in the fourth Test, taking two wickets with the ball, then making 28 as a batsman among just a trio of teammates to get into double digits.
Following a brief spell late on the first day, he resumed the next day and removed Scott Boland edging to the keeper.
However, on the final ball of that over, he bowled a slower ball to the batsman and suddenly grabbed for his hamstring.
Atkinson was brought back for the fourth Ashes Test having missed of the third.
