Paceman Atkinson Adds to the English team's Fitness Concerns.

'Serious blow' for England after Atkinson leaves the field due to a hamstring issue.

Gus Atkinson further complicated the injury concerns plaguing England after leaving the playing area on the second morning of the fourth Ashes Test in the Ashes series.

The pace bowler felt a problem in his hamstring after the final ball in his spell on Saturday.

Team management reported the 27-year-old felt some "soreness" and would spend time on the sidelines in order to be assessed "during the day".

The concluding match of the tour at the SCG begins this coming Sunday.

The English side has already lost fast bowlers one seamer to a knee injury and Jofra Archer to a side strain during this series.

Matthew Fisher was called up as injury reinforcement.

His form was underwhelming early in the series, claiming a mere three wickets.

He was left out for the Adelaide match, then recalled for the Boxing Day match to fill the void.

The county bowler showed better form in Melbourne, taking two wickets with the ball, before adding 28 with the bat among just a trio of England players to get into double digits.

After bowling one over at the end of day one, he returned for the second day's play and dismissed the nightwatchman Scott Boland caught behind.

Yet, on the final ball of the fifth over, he bowled a change of pace to the batsman and promptly felt his left hamstring.
