Seamer Atkinson Compounds the English team's Injury Worries.
'Significant concern' for England after Atkinson leaves the field due to a hamstring issue.
Gus Atkinson added to England's injury problems when he left the field early on day two of the Boxing Day Test against Australia.
The pace bowler pulled up with his left hamstring post-delivery in his spell at the MCG.
Team management stated Atkinson reported "discomfort" and would spend time off the field for further assessment "during the day".
The concluding match of the series at the SCG starts on Sunday, 4 January.
The English side has previously lost fast bowlers one seamer with a knee problem and another paceman with an abdominal strain on the current trip.
A replacement bowler was added to the party to provide backup.
His form was underwhelming in the opening two Tests, claiming a mere a handful of scalps.
He was left out of the third Test, only to be brought back for the Melbourne Test as Archer's replacement.
Atkinson improved at the MCG, taking two wickets during the host's first knock, then making 28 as a batsman among just a trio of English batsmen to reach double figures.
After bowling one over at the end of day one, he came back for the second day's play and had nightwatchman Scott Boland caught behind.
Yet, at the end of the fifth over, he delivered a change of pace to Travis Head and promptly felt at his leg.
Atkinson returned to the side for the Boxing Day Test having missed the Adelaide game.
