Maybe you should get to see a full season of HS to see what actually happens. He sat out the rest of the week of practices.
The riskiest time after a concussion is the several hours afterwards. Brain is susceptible, judgment and movement is impaired, and, well, you should know this already.
Any doc that "let him come back in, then sit out all week" is placing children at a very huge risk. I cannot believe a doc actually did this.
If you embellished, just a little, and he took a hard knock and you wanted to save face on the QB side by citing a concussion, just own it. But you're trashing the team doctor here, man, and I highly doubt he'd like that. You're saying he endangered the lives of children by letting them play after diagnosing them. Doctors lose their license for things like that, man.
If you stretched things, just own it. Otherwise, you're trashing that doc publicly in a big way, accusing him of this, man.
