Rybakina out of WTA Finals with viral illness; Kostyuk replaces defending champion

World No.1 Elena Rybakina, the defending champion, has withdrawn from the 2026 WTA Finals in Indian Wells with a viral illness, abandoning her title defence hours before the season-ending tournament was due to begin on Sunday. The Kazakh said she was “not physically ready to compete” and needed rest before returning in 2027.

The WTA confirmed the withdrawal on medical grounds, identifying a viral illness as the official reason, and ESPN India reported the world No.1 was out. She was due to be the event’s biggest name. Ukrainian Marta Kostyuk replaces Rybakina in the field, and her opening round-robin assignment is a meeting with reigning Wimbledon champion Linda Noskova.

The draw, released before the news broke, had Rybakina opening her title defence against Coco Gauff. Four-time WTA Finals participant Jessica Pegula and Noskova completed the group, so with Rybakina out Kostyuk is the late addition to a list that still includes Gauff and Pegula. Aryna Sabalenka’s tie against Mirra Andreeva is unaffected by the withdrawal.

A season of injuries and a strange final evening

For Rybakina, the exit is the latest interruption in a season repeatedly marked by injuries, as Sports Illustrated noted. Just moments before the withdrawal was confirmed, she sat for an interview that was posted online. Fans reacted furiously, calling the decision to post it “very unprofessional” and comparing the viewing experience to a “horror movie”. The interview, and the withdrawal minutes later, gave the final hours before the event a strange air.

Fatigue debate and prize money

The Professional Tennis Players Association (PTPA) used the moment to press its concerns, reiterating on Monday its criticism of the tennis schedule. Its statement tied the withdrawal directly to the demands of the tour calendar, and player fatigue has been the association’s running theme all season.

There is also money on the line, and the withdrawal will cost Rybakina heavily. Prize money at the event is down 35 per cent. The SPORTbible reported the men’s end-of-year event in Turin will pay its participants more than the WTA Finals does in 2026, with Taylor Fritz having missed out on large paydays after failing to qualify this year.

Reaction among players came quickly. Sabalenka was among the first to respond, Kursiv Media reported, while former champion Marion Bartoli picked her winner in the aftermath, Yahoo Sports reported.

The season-ender tips off on Sunday at Indian Wells with the draw reshuffled: Sabalenka against Andreeva, Kostyuk against Noskova, and no Rybakina anywhere on the schedule. Gauff and Pegula now contest a group missing its biggest name. The defending champion has said she returns in 2027. Until then, the title she was meant to defend is up for grabs.
