The 27-year-old French Open champion suffered his earliest exit at a major when he was stunned by Belgium's Steve Darcis on the first day of Wimbledon.
His straight-sets defeat to Darcis, ranked 135th in the world, led to speculation about the impact of the clay-court season on a previous injury, an inflammation of the knee cap, which curtailed Nadal's 2012 campaign.
But his uncle and coach Toni has insisted that the 12-time Grand Slam champion will ease himself back into his training regime in time for the US Open, which begins on August 26.
"Rafa will come back. He has no fear of the (hard court) surface - he has nothing more to lose," Toni Nadal said.
"Currently Rafa is doing physical training, but no racquet workouts.
"The break is important - he has played enough."
According to his uncle, Nadal, who is at home in Mallorca, will return to the tour on August 5 when he plays at the Montreal Masters, then Cincinnati, which starts August 12, before the US Open in New York.
Prior to Wimbledon, Nadal had reached the final of all nine tournaments he had entered since his return from a seven-month injury lay-off, winning seven of them -- including his eighth French Open title and the Masters in Indian Wells.
