Rafael Nadal has withdrawn from his BNP Paribas Open semifinal match with Roger Federer due to a right knee injury.
"I warmed up today, and I felt that my knee was not good to compete at the level I needed to compete in (the) semifinals," Nadal said.
Nadal sounded dejected about his latest injury, saying it's "tough for me to accept all these things that I'm going through in my career" but adding that he needs to be "positive and grateful" for what tennis has offered him.
Federer will face either Milos Raonic or Dominic Thiem in the Indian Wells final.
