Did Seahawks follow rules on concussions?

The NFL said Friday it is investigating whether the sport’s concussion-evaluation procedures were followed properly with Seattle Seahawks quarterback Russell Wilson during Thursday night’s game against the Arizona Cardinals.

“A thorough review is underway,” the league said in a statement.

Under league rules, a player with concussion- related symptoms must be examined and cleared by a doctor or independent neurological consultant before returning to a game or practice.

On Thursday, Wilson left the game after being sent to the sideline by referee Walt Anderson. Wilson sat in the area of the medical tent on the Seahawks’ sideline. But he got up, apparently before the medical staff had a chance to examine him and returned to the game after missing only one play.

Following that Seahawks possession, Wilson returned to the sideline and went into the medical tent. He returned to the game the next time the Seahawks had possession and finished the game.

Under an agreement announced last year, the NFL and NFLPA each appoint a representative to monitor compliance and investigate potential violations.

If there is disagreement, a thirdparty arbitrator is brought in to conduct a review and issue a report.

A team can be fined up to $150,000 for a first violation of the concussion protocols. Higher fines and the potential loss of draft picks also are possible. NFL commissioner Roger Goodell is in charge of any discipline.

“The parties consistently review the Concussion Protocol to ensure that players are receiving care that reflects the most up to date medical consensus. The new policy sets forth disciplinary action against a club should a member of its medical staff or other employee fail to follow the Concussion Protocol,” the league and union said in last year’s joint written announcement.
