It is not for us to know what goes on in the blue medical tent, until it is. The tents are what the league said is a privacy measure (and also what they didn’t say: a handy way to better control the narrative regarding head injuries, specifically) that was instituted this season and used across the NFL and if privacy is the actual goal, they’ve been effective.
They’ve also highlighted a lot of reasons why the NFL’s safety measures are still a joke. Players have had the tent pulled up around them, then immediately exited without undergoing any kind of medical test or treatment.
