Given that we got a pass on whether their primary source of fame was politics, we'll probably get a pass on this as well, if sports is indeed the other thing.
It is important to remember though, that the initial pass was on "arts or politics". If it was, say, an actor who is also a politician, that would have gotten a "yes" because their primary source of fame is clearly at least one of those. So asking about sports is a good idea.
