England Test Captain Ben Stokes was carried off the field on Sunday while playing for Hundred outfit Northern Superchargers.
All-rounder Stokes, 33, suffered an apparent hamstring injury in their match in Manchester and was accompanied into the stands by two Superchargers staff members.
He got injury on his left leg while in pain on the floor having hit a quick single. England begin the first of their three-match Test series with Sri Lanka on August 21, at the same Old Trafford ground.
