Actor Chris Evans is sending a "Captain America" shield to the Wyoming boy who saved his little sister from an attacking dog.
Evans praised six-year-old Bridger Walker as a hero in an Instagram post, saying what Walker did was brave and selfless.
Walker had stepped between the dog and his four-year-old sister and ended up needing 90 stitches in his left cheek.
Walker told his dad he saw the dog charging and said, "If someone had to die, I thought it should be me".
