Seamer Gus Atkinson Compounds England's Fitness Worries.
'Significant concern' for the English camp after Atkinson is forced off with a hamstring injury.
The English seamer further complicated England's injury problems when he left the playing area on the second morning of the fourth Ashes Test against Australia.
The pace bowler felt a problem in his hamstring post-delivery that he bowled during the morning session.
Team management reported Atkinson felt some "soreness" and would spend time on the sidelines in order to be assessed "over the next few hours".
The concluding match of the tour beginning on 4 January gets underway on Sunday, 4 January.
England have previously lost fast bowlers Mark Wood with a knee problem and another paceman to a side strain on the current trip.
A replacement bowler was added to the party as cover for Wood.
His form was underwhelming during the first two matches, claiming a mere a handful of scalps.
He was left out of the third Test, then recalled for the Boxing Day match as Archer's replacement.
Atkinson showed better form in Melbourne, taking two wickets in Australia's first innings, and scoring 28 runs while batting among just a trio of teammates to reach double figures.
Post a single over at the end of day one, he came back for the second day's play and removed Scott Boland edging to the keeper.
However, on the final ball of that over, he sent down a variation to Travis Head and promptly felt his left hamstring.
Gus Atkinson returned to the side for the fourth Ashes Test after being left out the Adelaide game.
