Serena Williams once again battled through the pain barrier to advance at the Australian Open on Thursday, but this time the American third seed's injury was entirely self-inflicted.
After rolling an ankle during her first round win the 15-time grand slam champion hit herself in the face with her racket as she brushed aside Spanish teenager Garbine Muguruza 6-2 6-0.
It left her anxiously checking her mouth for damage.
'I think it happens to everyone, but I have never busted it wide open like that,' the five-time Melbourne winner told reporters after setting up a third-round meeting with Japan's Ayumi Morita.
'So, yeah, I was like, 'Oh, no. I can't have a tooth fall out.' That would be horrible.'.
