A hypothetical, but I am curious: Now what?

In our state the coach, given the absence of anyone else there on site, by default, serves in that capacity.
The coaches here know this. At least I've seen evidence that they're regularly made aware of this and, in fact, trained in concussion-awareness to a sufficient extent that we've been told to leave it in their hands should an analysis be prompted by us.
Other states, indeed, may differ.
