Serena Williams' declaration that she needed a "break" after losing her opening match in Charleston has left fellow Americans in a waiting game for Fed Cup.

The United States, following a defeat to Italy in the first round, hosts France in the World Group playoffs on April 19-20.

When Madison Keys was asked during Charleston if she would be playing the tie, she described her status as, "Probably. Maybe."

"After Serena saying she needs a month and a half off, we're all kind of like, 'Oh, okay. Fed Cup is in two weeks. So maybe you won't be there,'" explained Keys. "So we're kind of waiting to see what she says."

After her defeat, Williams said, "I need some weeks where I don't think about tennis and kind of regroup."

Venus Williams confirmed at Charleston that she would not be playing the tie.
