Wimbledon champion Krejcikova out of Australian Open

"I wanted to share a quick update regarding my withdrawal from the Australian Open," Krejcikova posted on X.

"Unfortunately, my back injury, which troubled me at the end of last season, is still not fully healed.

"It's disappointing because I love playing in Melbourne and have such great memories from reaching the quarter-finals last year ... I'm working hard to get back to full health.

"I can't wait to see you on the court soon."

Krejcikova is a two-time Australian Open quarter-finalist and dual grand slam champion, having won the French Open in 2021 before adding the Wimbledon trophy in July.
