Injured Nadal turns up for practice ahead of Kyrgios showdown

Rafael Nadal turned up for practice at Wimbledon on Thursday a day after the 22-times Grand Slam winner played through an abdominal injury to beat American Taylor Fritz in an absorbing quarter-final. The Spaniard was back hitting forehands and backhands on the practice courts at Aorangi Park a day before his semi-final against Nick Kyrgios, and also went through his service motions.

Rafael Nadal and Nick Kyrgios will meet for a place in the Wimbledon final on Friday in what the Australian star claims will be "the most watched tennis match ever."

Nadal had said that he did not know if he would be fit to play against Australian Kyrgios, after appearing close to retiring mid-match against Fritz on Centre Court.

The 36-year-old Nadal, who is chasing a rare calendar-year Grand Slam after winning the Australian and French Open titles this year, also said he would undergo more scans on Thursday before deciding what to do.

Struggling with physical ailment, Nadal appeared close to retiring mid-match in his quarterfinal against Taylor Fritz on Wednesday but somehow found the will to win in four hours and 20 minutes.

Nadal's serve speed dropped drastically from the end of the second set against Fritz, after he took a medical time-out, but he still clinched the tie in a final-set tiebreaker. A third Wimbledon title, and first since 2010 on the manicured lawns, plus a U.S. Open triumph at Flushing Meadows in September would see the Mallorcan claim the calendar slam -- a feat last achieved in 1969 by Australian great Rod Laver.
