Rafael Nadal will take no further part in this year's
Laver Cup after withdrawing for 'personal reasons' following Roger Federer's emotional farewell.
Nadal was in tears as they lost to Jack Sock and Frances Tiafoe in Federer's swansong as two rivals but friends shared the court for the final time.
He has suffered with an abdominal injury for much of the summer which caused him to pull out at Wimbledon before further problems at the US Open and he said it's been a difficult few weeks.
"I'm not good, I'm not good," Nadal said. "The truth is these have been difficult weeks in that sense. Few, very few hours of sleep, a bit of stress in general, slightly more difficult situations than usual at home.
"As a result, well, I've had to deal with all that, which is a different pressure to the one you're used to in your professional life. But, well, luckily everything is good and we are much more calm. And in that sense, I've been able to come here, which for me was the most important thing."
