Dolphins quarterback Matt Moore was lucky to walk off the field, let alone finish Sunday's AFC wild-card showdown with the Steelers after a vicious hit to the head courtesy of Pittsburgh linebacker Bud Dupree in the second quarter at Heinz Field.
But should Moore have been allowed to re-enter the game after just one play?
The NFL announced on Monday it will review relevant documents and video, as well as interview the parties involved to determine whether the league's concussion protocol was followed properly following the hit.
The NFLPA also said it is looking into the matter.
Dupree destroyed Moore with a helmet hit to the chin that kept the signal caller on the ground for several minutes before he was helped off the field. Moore appeared to grab his back in pain but insisted he did not lose consciousness.
The announcement notes that initiation of the review does not mean the league has drawn conclusions as to whether the protocol was followed.
Should the Dolphins be found guilty of not following concussion protocol, it could result in a fine of up to $150,000 for a first-time offense.
Fines are set to a minimum of $100,000 for subsequent violations and could also require a loss of draft picks, should it be determined that a club's medical team failed to follow the protocol due to competitive considerations.
