Paceman Gus Atkinson Compounds England's Fitness Concerns.
'Major setback' for the touring side after Atkinson goes off with a hamstring injury.
The English seamer added to England's injury problems when he left the field on the second morning of the fourth Ashes Test in the Ashes series.
The pace bowler felt a problem in his left hamstring after the final ball of the fourth over at the MCG.
Team management indicated Atkinson had experienced "tightness" and required time off the field to undergo evaluation "in the coming hours".
The final Test of the series in Sydney gets underway this coming Sunday.
The English side has already lost key quicks Mark Wood due to knee trouble and Jofra Archer because of a side injury on the current trip.
A replacement bowler was brought into the squad as injury reinforcement.
The seamer had a tough time in the opening two Tests, taking just a handful of scalps.
He was dropped for the Adelaide match, then recalled for the fourth Test to fill the void.
The county bowler improved at the MCG, taking two wickets in Australia's first innings, and scoring 28 runs with the bat as one of just three England players to reach double figures.
Following a brief spell in Australia's second innings, he returned on Saturday morning and removed Scott Boland taken by the wicketkeeper.
Unfortunately, on the final ball of his spell, he sent down a change of pace to the batsman and suddenly grabbed at his leg.
Gus Atkinson was recalled for the fourth Ashes Test having missed the Adelaide game.
