The first time he got checked out, he called to the trainers himself right after the play. You can see him pointing to his head & yell something toward the sideline.
The 2nd time was worse, he immediately grabbed the back of his head with both hands & looked to be really feeling it.
These weren't questionable situations where checking him for concussion seems stupid, he was rocked. I can't believe he got back in after the first one, let alone the 2nd.
