Stokes dived forwards and clung on at long-on but immediately shook his left hand in distress before leaving the field for treatment. He did not bowl for the rest of the innings before making a three-ball duck when he batted.
An England and Wales Cricket Board spokesperson said: “We are aware (of Stokes’ injury) and he will be assessed over the coming days on the extent of the seriousness of the injury. At that point we will confirm the next steps.
“In addition, ECB medical and our UK hand specialist consultant are both involved.”
