wide standard? I know many HS have the "Impact" test. You can't start practicing until you pass that, then there is a 3 day return to practice protocol that the players have to pass before participating in contact. I assume college is at least similar, meaning Hall has passed any baseline tests and has been cleared for practice, but needs to make it through those practices without any returning symptoms before playing again. If thats the case, then the fact that he was practicing yesterday is actually a pretty good indicator that he has a good chance to be cleared to play on Saturday.
