England star Anderson pulls up during Lancashire match
England bowler James Anderson was forced out of county action for Lancashire with an injury on Tuesday - less than a month before the Ashes opener.
Anderson is set to be a key member of the England team against rivals Australia in a series that begins with the first Test at Edgbaston on August 1.
But the country's all-time record wicket taker pulled up while bowling against Durham at Sedbergh.
Anderson tried three times to complete the over but was ultimately forced off to be replaced by Josh Bohannon.
The 36-year-old claimed his 950th first-class wicket on day two of the County Championship Division Two match on Monday.
