A. Zverev is confident his ankle will hold up during the Australian Open after hurting himself during a practice session. "The ankle is fine. It's just a little bit swollen. I didn't actually twist it, I just kind of went over it a little bit. Actually what happened was a bone pushed against another bone. There was inflammation between those two bones. I'm fine. I'm going to play with the tape. It's just a little bit uncomfortable but it's nothing that can get worse or anything like that. I'm actually quite relaxed about it."
