'Significant concern' for England after Atkinson goes off suffering a hamstring problem.
The pace bowler added to the injury concerns plaguing England upon exiting the ground on the second morning in the Melbourne Test in the Ashes series.
The right-arm seamer experienced discomfort in his left hamstring post-delivery in his spell during the morning session.
Team management reported Atkinson had experienced "tightness" and was to take time away from the action to undergo evaluation "in the coming hours".
The series decider of the tour beginning on 4 January gets underway on Sunday, 4 January.
The visitors have previously lost strike bowlers one seamer due to knee trouble 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, taking just a handful of scalps.
He was left out of the third Test, then recalled for the fourth Test to fill the void.
The county bowler improved at the MCG, bagging two scalps with the ball, and scoring 28 runs with the bat among just a trio of England players to reach double figures.
After bowling one over in Australia's second innings, he resumed the next day and had nightwatchman taken by the wicketkeeper.
Unfortunately, on the final ball of the fifth over, he bowled a variation to the batsman and immediately felt at his leg.
The English bowler was brought back for the Melbourne match having missed the previous Test.
