Seamer Atkinson Adds to the English team's Fitness Worries.
'Serious blow' for England as Atkinson is forced off suffering a hamstring problem.
Gus Atkinson added to the fitness woes of the England squad after leaving the ground during Saturday's play of the Boxing Day Test in the Ashes series.
The right-arm seamer pulled up with his left hamstring post-delivery in his spell at the MCG.
Team management indicated the 27-year-old felt some "soreness" and was to take time away from the action for further assessment "in the coming hours".
The concluding match in this Ashes battle in Sydney gets underway on Sunday, 4 January.
The visitors have already lost fast bowlers Mark Wood due to knee trouble and Jofra Archer to a side strain during this series.
A replacement bowler was added to the party as injury reinforcement.
His form was underwhelming in the opening two Tests, taking just a handful of scalps.
He was left out of the third Test, then recalled for the Boxing Day match in the playing XI.
Atkinson showed better form in Melbourne, taking two wickets in Australia's first innings, and scoring 28 runs while batting as one of just three teammates who passed ten runs.
Following a brief spell at the end of day one, he came back on Saturday morning and dismissed the nightwatchman taken by the wicketkeeper.
Yet, towards the conclusion of that over, he bowled a variation to Travis Head and immediately felt his left hamstring.
The English bowler was brought back for the Melbourne match following his omission the previous Test.
