Rafael Nadal withdrew from the BNP Paribas Open on Saturday due to knee pain, the tournament confirmed. Nadal was slated to face Roger Federer in the tournament semifinal on Saturday evening in Indian Wells, Calif.
“I warmed up today and I felt that my knee was not good to compete at the level I needed to compete in semifinals," Nadal said in a statement. "It’s tough for me to accept all these things that I’m going through in my career. Sometimes I feel sad because I’m in a disadvantage to all my opponents."
"[I need to] be positive and grateful for all the things tennis has given to me.
