Third seed Serena Williams has laughed off suggestions that she will withdraw from her second-round match at the Australian Open.

The American took a tumble during her straightforward victory over Edina Gallovits-Hall and required heavy strapping to her ankle.

However, Williams joked after the game that only "something fatal" will prevent her from continuing in Melbourne.

"Oh, I'll be out there," said Williams. "I mean, unless something fatal happens to me, there's no way I'm not going to be competing.

"I'm alive. My heart's beating. I'll be fine. I've played this tournament with so many injuries and was able to come off pretty on top.

"So for me it's just another page and a great story to tell the grandkids one day."

Williams will either play Magdalena Rybarikova or Garbine Muguruza.
