Indian Wells: Serena Williams pulled out of her Indian Wells semi-final, 14 years after her sister Venus withdrew at the same stage to spark a fan uproar that led to a Williams boycott of the event.

Serena withdrew moments before her scheduled semi-final match on Friday night with a right knee injury, ending her hopes for a storybook finish after she made the decision several months ago to finally return to the joint WTA and ATP tournament.
