Seahawks quarterback Russell Wilson was not happy when referee Walt Anderson sent him to the sidelines after taking a hit to the head in the third quarter of Thursday's game against the Cardinals. Anderson was doing his job; if he suspected Wilson might have suffered a concussion, it's his right to have the medical staff perform a concussion check.

And according to the league's concussion policy, a player believed to have concussion symptoms cannot return to "practice or play" until he is cleared by the team physician and an independent neurological consultant.

But when Wilson came to the sidelines, he wasn't evaluated in the blue medical tent. We know this because he went into the tent alone and emerged seconds later.
