QA-OB-6: A player in my group foot-faulted and was called on it (and seconded). Their throw went OB. Do they get a warning, a penalty, or two penalties?

A player’s first stance violation results in a penalty throw. In this case, there were multiple violations. Normally, the first violation to occur is the one that counts. In this case, that’s the foot fault (though it doesn’t really matter as it’s one penalty throw either way). There’s no re-throw, so the disc is played as OB. Since a player cannot receive penalty throws for multiple violations on a single throw, there’s just one penalty throw.
