Defending champion Rafael Nadal has withdrawn from Wimbledon after failing to recover from injury.

Nadal has been suffering from chronic tendinitis, a condition that gives him aching knees and forced him out of the Queen’s Club tournament leading up to Wimbledon. The injury is also believed to have played a role in his shock fourth round loss to Robin Soderling at the French Open.

Nadal’s withdrawal makes the top seeds for the event Roger Federer and Englishman Andy Murray.
