Nadal, Djokovic both reach Miami final via walkover
Both advanced when their semifinal opponents withdrew for health reasons. They'll play for the title Sunday in their 40th career meeting and their first of 2014.
Djokovic received a walkover for the second time in the tournament when Kei Nishikori withdrew because of a left groin injury. Four hours later, Tomas Berdych withdrew before his match against Nadal because of gastroenteritis.
The No. 2-ranked Djokovic will be bidding for his fourth Key Biscayne title. Regardless of the result, Nadal will remain No. 1 next week.
Nishikori won a grueling three-set match against Roger Federer on Wednesday night and also won a three-setter against David Ferrer in the fourth round, when he saved four match points.
Nishikori tweeted the news after he tried to practice before the match.
"Very disappointed and I am obviously very sorry for any fans," he said.
The two cancelled matches left the tournament with only two women's doubles matches.
Former No. 1 Martina Hingis advanced to her first doubles final since 2007 when she and Sabine Lisicki beat Cara Black and Sania Mirza 6-3, 6-4.
