Rafael Nadal says he doesn’t know when he will play again after losing in the fourth round of the US Open.
“I have to go back. I have to fix things, life, then I don’t know when I’ll be back,” said the 22-time Grand Slam champion.
“I’ll try to be mentally ready. If I feel like I’m ready to compete again, I’ll be there.”
Nadal is planned play in Laver Cup, alongside Roger Federer, Novak Djokovic and Andy Murray from September 23-25 in London.
The loss to 22nd seed Tiafoe was Nadal’s first Grand Slam loss this year.
The US Open, which he hoped to win for the fifth time, was only the second tournament he had competed in since withdrawing from the Wimbledon semi-finals with a stomach injury.
After an opening loss to Borna Coric in Cincinnati, Nadal headed to New York and never quite felt comfortable with his first two wins.
The second seed improved against France’s Richard Gasquet but was overwhelmed by Tiafoe in front of a raucous home crowd in New York.
“The difference is simple: I played a bad match and he played a good match,” said Nadal, who won the Australian Open and French Open titles that year.
“I wasn’t able to keep a high level of tennis for a long time. I wasn’t fast enough in my movements. He could take the ball too many times very early, so I couldn’t push him back.
“Tennis is a positional sport. You have to be very, very fast and very young. I’m not in that moment anymore.”
Nadal’s defeat – along with that of Marin Cilic – means there will be a first Grand Slam winner in men’s singles.
