Miami Dolphins star quarterback Tua Tagovailoa is one fearless man. It already takes a lot of courage to simply put on a uniform and play football at the highest level, but Tagovailoa takes braveness to a new level with his burning desire to continue partaking in the violent sport on the field despite the head injuries he's suffered in the past.

Tagovailoa got hurt when he collided with Buffalo Bills defensive back Damar Hamlin on Sept. 12. He ran for a first down and initiated contact by lowering his shoulder into Hamlin instead of sliding, which prompted his teammates to have talks with him about protecting himself moving forward.
