Rafael Nadal still hasn't picked up a tennis racket since he limped out of Wimbledon nearly three months ago and he has no idea when he'll return to competition.
Nadal has been on the sidelines since his shock second round loss at Wimbledon to the Czech Lukas Rozol, and he's been receiving treatment for a torn tendon in his left knee.
26-year-old Nadal has missed the London Olympics, where he was to have been Spain's flagbearer, the Masters events in Toronto and Cincinnati and the US Open, but he says he won't be returning to tennis until he's 100 percent fit.
He's been swimming every day and working out in the gym.
