Nick Kyrgios has pulled out of Friday’s highly anticipated quarterfinal clash against Roger Federer because of illness. He had won his only previous matchup against Federer, a second-round meeting at the 2015 ATP Masters 1000 Madrid, and was coming off a victory over world No. 2 Novak Djokovic.

In a tweet, Kyrgios stated that he was unable to play because of possible food poisoning.

This ends a very successful BNP Paribas Open run for the 21-year-old Australian, who had yet to drop a set in the tournament, something he attributed to his improved mental toughness and renewed commitment to the game. After a frustrating Australian Open run, it seemed that Kyrgios had begun to turn his season around with two consecutive wins over Novak Djokovic and a string of positive results.

With the walkover Federer secures a trip to the semifinals of Indian Wells for the tenth time in his career and is set to face either Jack Sock or Kei Nishikori.

“We wish him a speedy recovery, and are looking forward to the remaining matches coming up today,” a tournament spokesman said in a news release sent via email.

The 18-time Grand Slam champion also sent his best to Kyrgios.
