Two of tennis' biggest legends, Roger Federer and Rafael Nadal, are both retired from the sport, but that doesn't mean fans won't see them playing on a tennis court ever again.
There's been chatter about 20-time major champion Federer and 22-time major champion Nadal possibly joining a senior tour of sorts in the future. Since Nadal did only retire last November, this idea probably isn't at the top of his priority list at the moment, as he likely wants to enjoy retirement for a bit.
