Defending champion Elena Rybakina has withdrawal from the 2026 WTA Finals on the eve of the season-ending tournament citing a medical issue.

The world No 1 was set to face Linda Noskova in the tournament's opening match on Sunday. Her place in the season-ending tournament will now be taken by Marta Kostyuk.

In a statement, the three-time Grand Slam winner said: "I am really sad to inform all my fans and supporters that I unfortunately have to withdraw from the WTA Finals this year.

"I've had an incredible season but my body is just not physically ready to compete. I'm going to spend some time resting and recovering at home and getting myself ready for the 2027 season.

"The WTA Finals is a very special tournament and I wish everyone the best of luck this week. Can't wait to be back in Indian Wells in March!"
