Rafael Nadal plans to test his fragile knee on the hard courts at Indian Wells to determine his playing schedule for the rest of the spring.
The 11-time Grand Slam champion feels encouraged about his comeback from injury after the past week, when he finally felt he could move freely. He dominated fellow Spaniard David Ferrer, the world's fourth-ranked player, to win the Mexican Open on Saturday.
Still, that was on clay, the only surface Nadal has competed on after missing seven months with a left knee injury. Hard courts put much more strain on his body, and he'll see how he copes with that starting later this week in California.
Nadal plays Juan Martin del Potro in an exhibition on a hard court at Madison Square Garden on Monday.
