The news raised immediate concerns about Tagovailoa's health after the Dolphins quarterback was hospitalized in September because of a second head injury in two games. Several ex-NFL players in the media urged the league, the Dolphins, and Tagovailoa on Monday to ensure he doesn't play again this season.
According to neuroscientist and famous concussion doctor Chris Nowinski, no NFL player has ever had three diagnosed concussions in a single season.
This is his second time in the protocol this season. Back in week four, during a terrifying moment while playing the Cincinnati Bengals, he took a brutal hit that left him motionless on the field for several minutes. He was hospitalized for a short time and only missed two weeks. This came just four days after he was rocked by a brutal hit while playing the Buffalo Bills. Though he didn't enter the protocol after that game, he was impaired, which led to serious questions for the Dolphins and the league after the incident versus Cincinnati.
