Wimbledon: 'I am worried' – Nadal admits he is no sure thing to play in the semi-final

London, July 7: Rafael Nadal says he does not know if he will be able to play in his semi-final against Nick Kyrgios after aggravating an abdominal injury during his five-set victory over Taylor Fritz.

Nadal, 36, has been vocal about his struggles physically during the tournament, but had been determined to push through the pain in an effort to keep his chances at the calendar slam alive, having already won this year's Australian Open and French Open.

During his quarter-final win against Fritz, family members were imploring Nadal to retire from the match as his clear discomfort appeared to be getting the better of him at times.

He admitted in his post-match media appearance that his condition worsened during the match, saying he will prioritise his health if he has to make a tough decision.

"I don't know [if I will be able to play] – I am going to have some more tests, but it is difficult to know," he said.

"I had these feelings for a couple of days, but without a doubt, today was the worst day. There has been an important increase of pain and limitation.

"I am worried. I don't have a decision. I need to know different opinions and I need to check everything the proper way.

"There is something more important than winning Wimbledon, and that is health."

The winner between Nadal and Kyrgios will face the winner of Novak Djokovic's semi-final against Cameron Norrie in the decider.
