An investigation into the concussion quarterback Tom Savage suffered earlier this month has cleared the Texans but has resulted in changes to the NFL's concussion protocol.
Led by Dr. Allen Sills, the NFL's chief medical officer, and Dr. Thom Mayer, the NFL Players Association's medical director, an investigation was conducted after Savage was injured in the Dec. 10 loss to San Francisco at NRG Stadium.
In a joint statement released Friday, the NFL and NFLPA said, "The parties have both concluded that while the medical staff followed the Protocol, the outcome was unacceptable and therefore further improvements in the Protocol are necessary.
