Gus Atkinson missed much of last summer through injury and was ruled out of the fifth Ashes Test with a hamstring problem
Gus Atkinson added to concerns over England's pace bowling by suffering a concussion during Surrey's County Championship match against Nottinghamshire.
In the week England could name their squad for the first Test against New Zealand, Atkinson was twice struck on the head by international team-mate Josh Tongue.
Batting in Surrey's first innings at Trent Bridge, Atkinson was hit in successive Tongue overs - with the second blow particularly nasty.
The 28-year-old was assessed on both occasions and batted on. He eventually called for more treatment and retired on 27, replaced in the match by Reece Topley.
