Fast bowler Atkinson Exacerbates the English team's Fitness Worries.

The pace bowler further complicated the fitness woes of the England squad after leaving the ground early on day two of the fourth Ashes Test against Australia.

The pace bowler pulled up with his left hamstring after the final ball of the fourth over on Saturday.

The England team reported Atkinson felt some "soreness" and would spend time away from the action for further assessment "during the day".

The concluding match in this Ashes battle at the SCG begins this coming Sunday.

The visitors have already lost key quicks one seamer due to knee trouble and another paceman with an abdominal strain during this series.

Matthew Fisher was called up as injury reinforcement.

His form was underwhelming during the first two matches, claiming a mere three wickets.

He was omitted of the third Test, only to be brought back for the Boxing Day match in the playing XI.

Atkinson improved at the MCG, bagging two scalps during the host's first knock, then making 28 while batting among just a trio of teammates who passed ten runs.

Following a brief spell in Australia's second innings, he returned for the second day's play and dismissed the nightwatchman edging to the keeper.

Yet, on the final ball of that over, he delivered a variation to the batsman and promptly felt for his hamstring.
