Luke Fletcher has been ruled out for the rest of the season after sustaining a head injury playing for Notts Outlaws against Birmingham Bears at Edgbaston on Saturday night.
Fletcher was assessed and treated at the ground before being quickly transferred to Queen Elizabeth Hospital, Birmingham for further investigations.
He stayed in overnight and was discharged on Sunday before returning yesterday (Tuesday) for further tests.
“Following consultation with doctors, Luke has been ruled out for the rest of the 2017 season to allow adequate time to recover and complete a monitored care plan to ensure he has a safe return to play,” said Director of Cricket Mick Newell.
“Whilst we are all obviously very disappointed, Luke's health is of paramount importance and comes first.
“We will continue to give him every support as he undergoes his recovery.”
