Rafael Nadal has withdrawn from the US Open as he continues his battle with knee tendinitis.
"Rafa has informed us that he will not be ready to compete at the US Open this year and has withdrawn from the tournament," read a statement from tournament director David Brewer today.
"We hope to see him back on the court soon and look forward to his return to New York next year."
Nadal had been dropping hints for weeks that his condition might not be improving.
The Spanish world No.3 played his last match on June 28, losing in the Wimbledon second round to Czech Lukas Rosol.
