Middlesex all-rounder Gareth Berg has been ruled out for the remainder of the season with a shoulder injury.
The 33-year-old had been recovering from an abscess in his shoulder in recent months, but his campaign has been brought to a premature end after a medical examination revealed a large rotator cuff muscle tear.
Berg will undergo surgery in the coming weeks to repair his injured shoulder.
Middlesex managing director of cricket Angus Fraser said: "This is obviously extremely disappointing news for Gareth and Middlesex. He is an extremely important player, in that he gives the team quality and balance.
"Gareth's presence has and will continue to be missed by the team and we all wish him a speedy and full recovery."
Berg's last game for Richard Scott's side came in their 10-wicket LV= County Championship Division One victory against Nottinghamshire in April.
