The injury kept the 20-time Grand Slam champion out of Wimbledon and the Tokyo Olympics this year and played a role in his shock third-round exit at the Washington Open last week.
“I have had this issue for a couple of months, as people know,” said Nadal, a five-time winner of the event, which was cancelled last year due to the COVID-19 pandemic.
“Of course, it is not a happy situation after all the success that I had here in Canada, not being able to play this year after missing a year.” He said the decision was a tough one but added that the most important thing was getting better so he could go back to appreciate his time on the court.
