Williams shrugs off injury scare  Serena Williams suffered an
injury scare at the Australian Open but insisted she would be
fit for her second-round encounter on Thursday.    "I'll be out
there," said the third seed. "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."   She added: "It
reminded me a lot of Brisbane. I thought 'oh no, not again'.
"But I've had such a good year that I don't think it's anything
negative. I just hope it's nothing serious because it was
serious last year."
