Seamer Atkinson Adds to England's Fitness Worries.
'Significant concern' for the English camp after Atkinson is forced off due to a hamstring issue.
The pace bowler added to the fitness woes of the England squad upon exiting the playing area during Saturday's play of the fourth Ashes Test against Australia.
Atkinson experienced discomfort in his hamstring immediately following a delivery of the fourth over at the MCG.
The England team reported the 27-year-old felt some "soreness" and required time on the sidelines in order to be assessed "in the coming hours".
The concluding match in this Ashes battle at the SCG begins at the end of the week.
England have previously lost strike bowlers one seamer with a knee problem and Jofra Archer to a side strain on the current trip.
Matthew Fisher was added to the party as cover for Wood.
The seamer had a tough time in the opening two Tests, claiming a mere three wickets.
He was left out from the previous Test, before being recalled for the fourth Test to fill the void.
Surrey's Atkinson showed better form in Melbourne, taking two wickets during the host's first knock, then making 28 as a batsman among just a trio of English batsmen to reach double figures.
Following a brief spell in Australia's second innings, he returned on Saturday morning and had nightwatchman taken by the wicketkeeper.
Yet, at the end of his spell, he sent down a variation to the batsman and suddenly grabbed his left hamstring.
Gus Atkinson was recalled for the fourth Ashes Test having missed the Adelaide game.
