A third Wimbledon crown will not be in the offing for Rafael Nadal this year.

Nadal announced Thursday that he was withdrawing from Wimbledon after failing to recover from an abdominal injury, ending his hopes of a calendar Grand Slam.

"Unfortunately, I have to pull out from the tournament," the dejected Spaniard told reporters at a hastily arranged news conference, less than 24 hours before his semifinal showdown against Australian Nick Kyrgios.

"As everybody saw yesterday (in the quarterfinal), I have been suffering with abdominal pain. I knew something was not okay there. Yeah, that's confirmed. I have a tear in the muscle in the abdomen.

Nadal won the Australian and French Opens back-to-back this year for the first time in his career and was bidding to become the first man since Rod Laver in 1969 to complete the calendar-year slam.

With the Spaniard's withdrawal, unseeded 27-year-old Kyrgios became the first Australian to reach the men's singles final at the All England Club since Mark Philippoussis in 2003.

Kyrgios will take on either top seed Novak Djokovic, who is bidding for a fourth straight and seventh overall title on the manicured lawns of Wimbledon, or local hope Cameron Norrie in Sunday's final. 

Their semifinal is scheduled for Friday.
