MADRID, June 9 (UPI) -- Rafael Nadal is undergoing treatment for tendonitis in both kneecaps but said he will travel June 16 to London ahead of the Wimbledon Championships.
Nadal, the world's top-ranked tennis player, withdrew from the Queen's Club tournament, an important grass-court tuneup ahead of Wimbledon and which Nadal won last year. He cited knee problems for pulling out.
