Surrey all-rounder Zafar Ansari undergoes second thumb operation

Surrey all-rounder Zafar Ansari has undergone a second operation on the thumb injury that ruled him out of England's tour of the United Arab Emirates last year.

The top-order batsman and slow left-armer dislocated the thumb on his bowling hand while fielding in Surrey's County Championship game against Lancashire last September, hours after earning a maiden international call-up for the tour to face Pakistan.

A Surrey statement read: "This operation was designed to help with the healing process and is related to the bottom joint of his thumb - which had been damaged previously and exacerbated by the incident at Old Trafford - not the top one, which he suffered an open dislocation of."

Surrey also announced former England fast bowler Jade Dernbach will miss the start of the county season because of a stress fracture in his back.
