Seamer Gus Atkinson Compounds the English team's Fitness Problems.
'Significant concern' for the touring side as Atkinson goes off with a hamstring injury.
The English seamer further complicated the fitness woes of the England squad when he left the playing area early on day two of the fourth Ashes Test against Australia.
The right-arm seamer experienced discomfort in his left leg after the final ball that he bowled at the MCG.
The England team indicated the 27-year-old felt some "soreness" and was to take time off the field in order to be assessed "in the coming hours".
The series decider in this Ashes battle in Sydney gets underway on Sunday, 4 January.
The visitors have previously lost key quicks Mark Wood due to knee trouble and Jofra Archer with an abdominal strain during this series.
Matthew Fisher was added to the party as cover for Wood.
The seamer had a tough time early in the series, taking just a handful of scalps.
He was left out of the third Test, before being recalled for the fourth Test to fill the void.
The county bowler performed better in the fourth Test, taking two wickets during the host's first knock, then making 28 with the bat among just a trio of English batsmen to reach double figures.
Following a brief spell in Australia's second innings, he came back on Saturday morning and removed Scott Boland taken by the wicketkeeper.
Unfortunately, towards the conclusion of his spell, he delivered a variation to the batsman and promptly felt at his leg.
Atkinson returned to the side for the Boxing Day Test having missed the Adelaide game.
