Durham's one-day captain Dale Benkenstein is set for a spell on the sidelines after injuring his shoulder.
The batsman needs on operation after hurting his shoulder whilst fielding during Durham's County Championship Division One victory over Surrey last week.
He will have an operation on Wednesday and it is not yet know how long he will be out for though Durham hope he will be back for the season's run-in.
A Durham statement read: "Dale Benkenstein will undergo shoulder surgery on Wednesday next week to repair a badly torn left rotator cuff tendon.
"Following the operation Dale will undergo a period of rehabilitation and could be available at the latter end of the season."
