Ajla Tomljanović has announced she will not play in next week’s Australian Open as she battles an ongoing knee injury.

Australia’s top female player, who made headlines around the world after beating Serena Williams on her farewell tour at the US Open, announced the decision via social media.

“It absolutely pains me to have to write this message but unfortunately I won’t be able to compete at this year’s Australian Open,” Tomljanović wrote.

“I’ve done absolutely everything in my power to get healthy but just ran out of time to heal and be 100% ready to compete at a high level.

“It’s been a very tough decision to make but I have to listen to my body.

“It’s no secret that this is my favourite place to play, so it hurts me to miss out on a great opportunity to play in front of my home crowd and to be surrounded by the incredible love and atmosphere.

“To all my Aussie fans, I wanna say thank you for always supporting me and cheering me on. I’m gonna miss you guys big time this year.”

More to come.
