Rafael Nadal says he does not know when he will play again after losing in the US Open fourth round.
The 36-year-old Spaniard was on Monday beaten in four sets by American Frances Tiafoe .
“I need to go back. I need to fix things, life, then I don’t know when I’m going to come back,” said the 22-time Grand Slam champion.
Nadal is scheduled to be playing in the Laver Cup,alongside Roger Federer, Novak Djokovic and Andy Murray, in London from 23-25 September.
The loss to 22nd seed Tiafoe was Nadal’s first defeat in a Grand Slam this year.
Nadal’s defeat – along with that of Marin Cilic – means there will be a first-time Grand Slam winner in the men’s singles.
The US Open, which he was bidding to win for a fifth time, was only the second tournament he had played since pulling out of the Wimbledon semi-finals with an abdominal injury.
