Desperate Housewives

Five desperate housewives - Tina, Sarah, Barbara, Francesca, and Victoria, were on a vacation in Brazil for the summer, so decided they could as well visit the Olympic Games in Rio. They bought tickets for several events, dressed up in their finest clothes, and went to the Olympic facility. However, once they got there, one of them wasn't allowed to enter. Which one?

Each of the housewives is wearing a ball patch from a popular sport - tennis (Tina), soccer (Sarah), basketball (Barbara), football (Francesca), volleyball (Victoria). Out of these five sports, only football is not part of the Olympic Games, and therefore the answer is Francesca.
