Seamer 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 upon exiting the field during Saturday's play of the fourth Ashes Test versus the Australians.
The right-arm seamer felt a problem in his left leg immediately following a delivery of the fourth over on Saturday.
The England team indicated Atkinson felt some "soreness" and was to take time off the field in order to be assessed "in the coming hours".
The series decider of the tour beginning on 4 January starts on Sunday, 4 January.
The visitors have been without key quicks one seamer with a knee problem and another paceman with an abdominal strain on the current trip.
Matthew Fisher was added to the party to provide backup.
The seamer had a tough time during the first two matches, taking just three wickets.
He was omitted of the third Test, then recalled for the Melbourne Test to fill the void.
Surrey's Atkinson showed better form in Melbourne, taking two wickets with the ball, then making 28 while batting being one of only three England players to reach double figures.
Post a single over at the end of day one, he returned the next day and dismissed the nightwatchman taken by the wicketkeeper.
Yet, on the final ball of the fifth over, he delivered a variation to Travis Head and immediately felt for his hamstring.
Gus Atkinson was brought back for the fourth Ashes Test following his omission of the third.
