INDIAN WELLS, Calif. -- Karolina Muchova has withdrawn from her 2026 FAGE WTA Finals group-stage finale with a gastrointestinal illness.

Diana Shnaider, No. 10 seed and second alternate, will replace Muchova face No. 3 Mirra Andreeva to begin play on Friday at Indian Wells. 

Regardless of the result vs. Shnaider, Andreeva has already secured first place in Group 2 with straight set wins over No. 6 Elina Svitolina and No. 2 Aryna Sabalenka. She'll face No. 5 Jessica Pegula for the first time on the WTA Tour Driven by Mercedes-Benz in the tournament's semifinals on Saturday.

Muchova finishes her 2026 season with a 41-14 record, and was eliminated from knockout stage contention with losses to Sabalenka and Svitolina. She won titles in Doha and Bad Homburg, and reached the final at Wimbledon.
