World No. 1 Aryna Sabalenka has withdrawn from next week's Porsche Tennis Grand Prix in Stuttgart, Germany, due to an undisclosed injury.

The four-time Grand Slam champion and 24-time WTA Tour winner said Thursday she sustained the injury after winning the Miami Open on March 28.

'I'm very sad to say that I won't be able to play the Porsche Tennis Grand Prix this year,' the 27-year-old Belarusian wrote in an Instagram story. 'I always love coming back to Stuttgart. The atmosphere, the fans, and the support I feel there are so special to me. And of course, I was really hoping to have another chance to fight for that Porsche.

'Unfortunately, I suffered an injury after Miami, and even though I tried everything to recover in time, I'm not ready to compete. I'm really sorry to miss this amazing tournament. Wishing everyone a great week in Stuttgart, and I hope to see you all again very soon.'

Sabalenka has never won the clay-court tournament in Stuttgart, losing in the final in 2021, 2022, 2023 and 2025.

Magdalena Frech of Poland moved into the draw with Sabalenka's retirement,

'We wish our four-time finalist a speedy and full recovery and warmly welcome Magdalena to the main draw,' read a tournament statement.

Sabalenka is off to a sizzling start in 2026 at 23-1 with singles titles at Miami, Indian Wells and Brisbane. Her only setback was a three-set loss to Elena Rybakina in the Australian Open final.

She is scheduled to compete in the back-to-back WTA 1000 tournaments in Madrid (April 21-May 3) and Rome (May 5-17).
