The Houston Texans came under heavy scrutiny in Week 14 when they allowed Tom Savage to re-enter a game against the San Francisco 49ers after he clearly suffered a head injury, but the team will not face disciplinary action over the situation. On Friday, the NFL and NFL Players Association announced that the Texans’ medical staff followed the league’s concussion protocol. Changes have since been made to the protocol, with the league saying in a statement that the outcome with Savage was “unacceptable and therefore further improvements in the protocol are necessary.” “The review showed that following a hard tackle, Mr. Savage was immediately removed from the game and evaluated for a concussion,” the statement read. “The Unaffiliated Neurotrauma Consultant (“UNC”) and team physician reviewed the initial broadcast video, saw the play and Mr. Savage’s response and followed the Protocol by performing a complete sideline concussion evaluation on Mr. Savage, which he passed. The slow-motion video, which focused more directly on the fencing posture, was not broadcast until after the doctors had begun the sideline evaluation and thus was not seen by the medical staff prior to the evaluation. The Texans medical staff continued to monitor Mr. Savage after the initial evaluation and shortly after his return to the game, identified symptoms that had not been present during the sideline evaluation and took him to the locker room for further evaluation.” Savage took a brutal hit from 49ers defensive lineman Elvis Dumervil near the end zone, and he could be seen shaking and seemingly having spasms after the play.
