Miami Dolphins starting quarterback Tua Tagovailoa suffered his second-documented concussion on Dec. 25 against the Green Bay Packers.
While Tagovailoa finished the game, he entered the protocol the next day and did not return for the remainder of the season. Tagovailoa suffered a concussion in Week 4 against the Cincinnati Bengals and did not return until Week 7.
"For concussion protocol, I think the team did me the biggest service throughout that... They were protecting me from myself. Me and my family are very thankful for the Dolphins.
