NFL Rumors: Tua Tagovailoa Speaking to Concussion Evaluation Investigators Tuesday

Miami Dolphins quarterback Tua Tagovailoa is speaking with investigators Tuesday as part of the NFL and NFLPA's inquiry into his concussion evaluation during and after a Week 3 matchup against the Buffalo Bills, according to ESPN's Marcel Louis-Jacques.
Tagovailoa was allowed to return against Buffalo after halftime despite hitting his head on the turf in the second quarter and exhibiting signs of a concussion, including stumbling as he was trying to jog back to the huddle for the next play.
While the Dolphins have received plenty of criticism for allowing Tagovailoa to return to that game, the 24-year-old said that he passed concussion protocol.
The NFLPA quickly launched an investigation into his concussion evaluation during the game and recently announced the firing of the unaffiliated neurotrauma consultant involved in that evaluation.
NFL Chief Medical Officer Dr. Allen Sills also promised that the full results of the investigation would be made public, per Pro Football Talk's Mike Florio:
"We want to be as transparent and open about this as possible. We certainly want to learn, to improve, to get better. And we want to be the best in the world at diagnosing and managing these injuries. And so if we find that we fell short, or if we find that there are things that we need to change, we will certainly be up front about doing that. We’ve done that before, and we will certainly do that again, if that’s what's indicated."
The Dolphins were also criticized for allowing Tagovailoa to play in Week 4 against the Cincinnati Bengals, just four days after the Buffalo game, after he was taken to the hospital on a stretcher following a scary hit that left him with head and neck injuries.
However, head coach Mike McDaniel told reporters that Tagovailoa passed concussion protocol every day leading up to Week 4 and also on game day:
"I have 100 percent conviction in our process regarding our players. This is a player-friendly organization and I make it very clear from the onset that my job here is for the players. I take that very seriously. No one in the building strays from that ... If there would have been anything lingering with his head, I wouldn't have been able to live with myself if I prematurely put someone out there and put them in harm's way.
"This is a relationship that I have with this human being. I take that serious. I wouldn't have put him out there if there was any inclination given to me whatsoever that he was endangering himself from that previous game."
Tagovailoa has since been diagnosed with a concussion and ruled out for Week 5 against the New York Jets. There is no timetable for his return.
The NFL and NFLPA reportedly intends to change the league's concussion protocol. It will "rule out players who exhibit gross motor instability" regardless of any other contributing factors, per NFL Network's Ian Rapoport and Tom Pelissero.
