INDIAN WELLS, Calif. — Defending champion Juan Martin del Potro has withdrawn from next month’s BNP Paribas Open because of a knee injury.
Del Potro said Wednesday through tournament officials that he’s been advised to rest by his doctors and he hopes to return to action soon. He defeated Roger Federer to win his first Masters 1000 title last year in the Southern California desert.
The fourth-ranked Argentine lost in the quarterfinals of last week’s Delray Beach Open in Florida. It was del Potro’s first tournament since injuring his knee at the Shanghai Masters in October.
Del Potro had already pulled out of this week’s Mexican Open in Acapulco, which he won last year. He also missed the Australian Open in January.
With del Potro’s withdrawal, Taro Daniel of Japan moves into the men’s draw.
The women’s draw already lost two-time winner Maria Sharapova, who withdrew with a shoulder injury.
The tournament runs March 6-17 in Indian Wells.
EASTBOURNE, England (AP) Andy Murray has lost in men’s doubles for the first time since returning from hip surgery in January.

PRAGUE — Two-time Wimbledon champion Petra Kvitova says she will decide later this week if she’s ready to play at the All England Club.
The 29-year-old Czech player injured her left forearm during training in Paris ahead of the French Open and has not played since. The injury prevented her from defending her title at the Birmingham Classic this week.
Kvitova wrote on Twitter that she was “Happy to tell you that my arm is improving and I just hit some balls on the beautiful grass for the first time.
The sixth-ranked Kvitova, who won the Wimbledon title in 2011 and 2014, reached the Australian Open final and won tournaments in Sydney and Stuttgart this year.
