Sark reported that both injuries (Quinn's chest, Hudson's ankle) wouldn't require surgery. As weird as it is, that means that both players will be active when they can tolerate the discomfort. You might re-aggravate an injury, but you won't make it worse by playing.
Quinn's collarbone is sore at the point where it meets his breastbone. Non-throwing shoulder. That could range anywhere from from "It still hurts to breathe" to "It feels fine". The day he decides it feels good enough to have a DT knock him to the ground on it is the day he's ready to play.
Card's ankle is an even more unknown quantity. It isn't structural, so if he can run on it, he's ready. That could have happened Wednesday, it may not happen until December. There's no such thing as a "typical ankle sprain".
Really, from UTSA's perspective, it doesn't really matter. All three QBs want to operate the offense in the same manner. Bijan is your first thought. Otherwise, read your passing formation versus the defense. Somebody will be open.
