Rafael Nadal has withdrawn from his Indian Wells semi-final against Roger Federer with a right knee injury.
The world number two received treatment to the knee during his gruelling quarter-final win over Russia’s Karen Khachanov on Friday.
The Spaniard looked in discomfort during the match and only had a brief practice session on Saturday.
Nadal and Federer, who have 37 Grand Slam titles between them, have not played each another since 2017.
Federer received a walkover to the final, where he will play either Austria’s Dominic Thiem or Milos Raonic of Canada.
