James Anderson forced off injured while bowling for Lancashire against Durham

England bowler James Anderson was forced to leave the field after pulling up in his run-up while bowling for Lancashire in their County Championship clash against Durham.

The 36-year-old, who claimed his 950th first-class wicket on Monday, stretched and attempted to run in three times to shake off the problem, but was forced to leave the action.

With the first Ashes Test against Australia less than a month away, any potential injury to England’s star bowler will be a major concern for the selectors.

While England’s one-day squad have been in World Cup action, Anderson has spent a prolonged spell with his county in preparation for the Ashes which begins at Edgbaston on August 1.

This match at Sedbergh School – the County Championship’s newest venue – is Anderson’s sixth game in the competition and his two wickets on Monday took his tally to an impressive 30 for the season.

The ECB provided an update on Anderson’s injury, saying: “Jimmy Anderson has sustained tightness to his right calf. He will take no further part in the game and will continue to be assessed.”
