The NFL has concluded that the Miami Dolphins did not properly follow concussion protocol with quarterback Matt Moore after a violent hit in the wild-card round of this year's playoffs.

Moore was down on the field after taking a shot underneath the chin from Pittsburgh Steelers linebacker Bud Dupree. He had to be helped to the sideline, but was cleared to return just one play later.

Rather than issuing discipline to the Dolphins organization, the NFL's official statement indicated that the club must have its staff review the protocol in place.

From NFL Network's Ian Rapoport:

The Miami Dolphins were notified in a letter co-signed by Dr. Hunt Batjey, Co-Chair of the NFL Head, Neck & Spine Committee and Dr. Thom Mayer, Medical Director for the NFLPA, that the NFL-NFLPA review determined that the Protocol was not strictly followed. The letter further advised the Dolphins that they must engage their staff in a full review of the Protocol and conduct additional education, if necessary. The Dolphins were also advised that any future deviation from the Protocol may result in enhanced discipline, including monetary fines assessed against the Club.

Moore, who was starting in place of an injured Ryan Tannehill, went on to finish the game after returning from the scary collision.
