The Facts: The Seattle Seahawks violated the NFL's concussion protocol Thursday night when they allowed Wilson to re-enter the game without going to the locker room and being cleared by a team doctor and an independent physician, a source close to the situation told ESPN's Adam Schefter.

Diehards Line: The NFL said on Friday a review is underway for a possible violation of the league's concussion policy Thursday night when quarterback Russell Wilson was sent off the field for a test. The Seahawks are expected to face consequences because once the official removed Wilson for the game to be examined, the star quarterback was required to go through protocol, and he did not. The Seahawks can be fined up to $150,000, although it's unclear what their penalty will be. The NFL announced Friday that it was conducting a "thorough review" of the situation. ... With backup Austin Davis in the game, NBC's broadcast showed Wilson running to the sideline and then sitting down in the area where the tent would be pulled over him. But Wilson got back up before medical officials had a chance to join him and then replaced Davis after one play. Wilson was on the field for two more plays before the Seahawks punted. During the change of possession, Wilson again entered the tent and remained there for a longer period of time. He was on the field when the Seahawks regained possession.
