Paceman Gus Atkinson Compounds England's Fitness Concerns.
'Serious blow' for England as Atkinson is forced off due to a hamstring issue.
The pace bowler added to England's injury problems when he left the field early on day two of the Boxing Day Test in the Ashes series.
The right-arm seamer pulled up with his left hamstring immediately following a delivery in his spell on Saturday.
The touring camp indicated the 27-year-old felt some "soreness" and was to take time away from the action in order to be assessed "in the coming hours".
The series decider in this Ashes battle beginning on 4 January begins at the end of the week.
The visitors have been without strike bowlers Mark Wood with a knee problem and Jofra Archer because of a side injury on the current trip.
Matthew Fisher was called up as cover for Wood.
His form was underwhelming during the first two matches, claiming a mere a handful of scalps.
He was omitted from the previous Test, before being recalled for the Boxing Day match as Archer's replacement.
Surrey's Atkinson improved at the MCG, bagging two scalps with the ball, and scoring 28 runs while batting among just a trio of England players to reach double figures.
Post a single over at the end of day one, he came back for the second day's play and had nightwatchman edging to the keeper.
Yet, towards the conclusion of his spell, he bowled a variation to Travis Head and immediately felt his left hamstring.
Atkinson was recalled for the fourth Ashes Test having missed the previous Test.
