American James Blake is set to miss the Australian Open for a second straight year after tournament director Craig Tiley posted the news on Twitter.
"Just got word that James Blake has withdrawn from the Australian Open and Brisbane. Sorry to hear this and we wish James all the best," Tiley tweeted.
The Brisbane starts on January 1 with the Australian Open starting on January 16.
Blake, currently ranked 59, also missed out last year amid a variety of fitness battles.
