Iga Swiatek’s Miami title defense is already over without hitting a ball. The world No. 1 withdrew from the second Masters of the season due to a rib injury.

“You know that in and after Doha I was struggling with a strong infection,” Swiatek said in a statement. “I was allowed to play, but a strong episode of tough cough led to a rib injury. We were trying to handle it and continue to play as long as it was safe for me. We were analyzing the data in the last days and my doctor prepared my diagnosis.

“Unfortunately, I’m still feeling a lot of discomfort and pain and I can’t compete.”

During her loss last week to Elena Rybakina, the Polish star brought up the issue.

“I’m also like not feeling 100% physically. I have a little like discomfort in my rib, and we’re going to consult with medical team. For sure I’m gonna use these days off before Miami, so actually I have one more day.”

Swiatek will return in a month for the clay.

“I will keep you updated about where I play next, because it depends on my process of recovering and the recommendation of my medical team,” she said. “I have the best team behind me, we only need some time to deal with the injury. It’s a truly difficult call to not play in Miami and BJKC, but health is the most important.”

With Sloane Stephens losing this evening, Victoria Azarenka is the lone former champion left in the women’s draw.
