A Martin Guptill drive has floored former Australian test bowler Joe Mennie in English county cricket.
Mennie, who played one test and two one-day internationals in 2016, was struck on the side of the head and fell still on the wicket as players and officials, including Worcestershire's Guptill, rushed to his aid.
The Lancashire bowler became the first player to be subbed out of a game with concussion.
Mennie reportedly deflected the ball towards his temple.
He walked off the ground unassisted after receiving medical attention during a lengthy delay.
