Week 4 started with a schocking image at Paul Brown Stadium. Tua Tagovailoa's, Miami Dolphins quarterback, had to exit the game against the Bengals due to a head and neck injury. After the concussion protocol failed, the NFL has decided to make huge changes in order to keep the players safe.

During the fourth Thursday Night Football of the 2022 NFL season, the Dolphins visited the Bengals in what seemed to be a very attractive game. Unfortunately, the match was momentarily suspended after Tua Tagovailoa had to exit directly to the hospital due to a head and neck injury.

But this was not the first time Tagovailoa had to leave due to this problem. Four days before, he got into the same situation against the Bills, but the Dolphins didn't follow the concussion protocol correctly and that's why the NFL has had enough.

NFL: Tua Tagovailoa's case has made the league to change the concussion protocol

A frightening image appeared in TNF of Week 4. Tua Tagovailoa was captured by Josh Topu, but he immediately fell to the ground in what appeared to be a concussion.

The problem grows when we go back four days. Against the Bills, Miami's quarterback had a similar situation, but the Dolphins didn't make a concussion check and Tagovailoa returned with "back injury" label on him.

The NFLPA is investigating if the Dolphins followed properly the concussion protocol and even one doctor has been already fired. But the league wants to do more in order to protect the players.

According to Judy Battista, NFL Senior Columnist, the league is preparing huge changes on the concussion protocol. The Players Association is really worried about the player's health and this could be a breaking point on this theme.

It is not the first time that this topic is surrounding the NFL, but probably one of the most controversial ones recently. It is expected that the NFL and the PA release a statement revealing what they will do in order to avoid more of these cases and properly protect the players.
