Fast bowler Atkinson Exacerbates the English team's Injury Worries.
'Serious blow' for England as Atkinson goes off with a hamstring injury.
Gus Atkinson further complicated the fitness woes of the England squad upon exiting the playing area on the second morning of the Boxing Day Test against Australia.
The right-arm seamer felt a problem in his left leg after the final ball that he bowled on Saturday.
Team management stated Atkinson reported "discomfort" and required time on the sidelines to undergo evaluation "during the day".
The final Test in this Ashes battle at the SCG gets underway at the end of the week.
The English side has already lost key quicks Mark Wood due to knee trouble and Jofra Archer with an abdominal strain on this Ashes tour.
A replacement bowler was added to the party to provide backup.
Atkinson struggled early in the series, taking just a handful of scalps.
He was dropped of the third Test, only to be brought back for the Melbourne Test in the playing XI.
Surrey's Atkinson showed better form in Melbourne, taking two wickets in Australia's first innings, then making 28 with the bat among just a trio of England players to reach double figures.
Following a brief spell at the end of day one, he came back on Saturday morning and had nightwatchman edging to the keeper.
However, towards the conclusion of his spell, he sent down a change of pace to the batsman and suddenly grabbed his left hamstring.
Gus Atkinson was recalled for the fourth Ashes Test after being left out the Adelaide game.
