This year's Wimbledon champion was forced to withdraw from the tournament after injuring his abdomen. "I'm very depressed."
After a day of self-reflection and consideration, health won out over the temptations of yet another title.
Rafael Nadal, the 22-time Grand Slam champion, pulled out of his semifinal match against Nick Kyrgios on Thursday.
"Under these circumstances, I believe I cannot win two matches," he said. "I am unable to help."
A news conference was held at the All England Club just after 2 p.m. Eastern, and Rafael Nadal explained that he was withdrawing because of an abdominal muscle injury.
"I was thinking about it all day," he admitted. "I don't see the point in going."
"I'm in a bad mood," he said, his voice breaking.
Nadal, who entered the tournament halfway to a Grand Slam and with a chronically injured foot, began feeling abdominal soreness a week ago.
The pain worsened, and he likely tore the muscle during his five-set quarterfinal win over Taylor Fritz on Wednesday.
