The 2026 WTA Finals have suffered another late withdrawal, with Karolina Muchova pulling out of her final Group 2 match against Mirra Andreeva due to gastrointestinal illness. The Czech was forced to withdraw shortly before Friday's scheduled encounter in Indian Wells, with fellow Russian Diana Shnaider stepping in as her replacement to face the already-qualified teenager.
Muchova confirmed the news in a statement, expressing disappointment at being unable to finish her first WTA Finals appearance on court. "Unfortunately, I have to withdraw from today's match due to gastrointestinal issues," she said. "It's not how I wanted to end my season, but there's a lot to be proud of and I'm already looking forward to next year."
The withdrawal brings an abrupt end to Muchova's campaign after two consecutive defeats against Aryna Sabalenka and Elina Svitolina. The Czech had already been eliminated from semifinal contention following her three-set loss to Svitolina, meaning Friday's match represented her final opportunity to register a victory at the season-ending championships.
It is also a disappointing conclusion to what had otherwise been an outstanding 2026 season. Muchova captured her first WTA 1000 title in Doha, won the Bad Homburg Open and reached her maiden Grand Slam final at Wimbledon. She finishes the year with a 41-14 win-loss record.

Diana Shnaider steps in against Andreeva
Diana Shnaider, the tournament's second alternate, was called upon to replace Muchova, giving her an unexpected opportunity to compete at the WTA Finals. The Russian will face her compatriot Andreeva in the final Group 2 encounter, having previously lost both of their meetings on the WTA Tour.
Andreeva had already secured first place in the group after defeating Elina Svitolina and Aryna Sabalenka in straight sets. The World No. 3 therefore remains guaranteed a semifinal place regardless of Friday's result, with Jessica Pegula awaiting her in Saturday's knockout round.

The change of opponent does not affect the qualification battle in Group 2, as the remaining semifinal spot will be decided later on Friday when Sabalenka faces Svitolina in a winner-takes-all encounter.
Muchova's withdrawal also marks her second unsuccessful attempt to compete at the WTA Finals. She had previously qualified in 2023 but was forced to withdraw before playing due to a back injury.
