Nick Kyrgios is disappointed after Rafael Nadal withdraws from Wimbledon, and he is concerned about the final.

Nick Kyrgios said he was "disappointed" when he learned Rafael Nadal had withdrawn from their Wimbledon men's singles semifinal,

and that he only got one hour of sleep on Thursday night and was a "rogue ball of energy" as he processed the news.

With Nadal withdrawing from their semifinal due to an abdominal injury, Kyrgios will face No. 1 seed Novak Djokovic in his first Grand Slam final on Sunday.

Kyrgios said on Friday that he was hoping for a "third chapter" after going 1-1 in his previous two Wimbledon matches against Nadal.

"My energy was so focused on playing [Nadal] and tactically how I'm going to go out there and play

 the emotions of walking out there, all that type of stuff," Kyrgios said, adding that he found out about Nadal's decision while eating dinner Thursday.

"But, you know, it wouldn't have been easy for him to withdraw... He only lost one match this year. 

He was probably going for all four. As a result, it would be difficult. I hope he improves."
