MIAMI GARDENS -- Miami Dolphins quarterback Tua Tagovailoa has cleared concussion protocol and will play Sunday against the Arizona Cardinals, coach Mike McDaniel said Friday.
Tagovailoa has been in concussion protocol since Sept. 12 after suffering the third concussion of his career during a loss to the Buffalo Bills. He was placed on injured reserve five days later and missed the team's next four games.
The league's leading passer from a season ago was cleared to return to practice this week, in accordance with NFL policy, and officially cleared protocol after practicing in full Thursday.
