Damar Hamlin was easy to spot on the sideline of the Buffalo Bills’ practice field Tuesday morning.
Most of the defensive players on the “blue” side wore helmets for the team’s optional workouts. Hamlin’s head was instead covered in a pink tie-dyed beanie with a Bills logo, a sign that the safety was not yet tackling teammates in summertime workouts.
It was the second on-field workout for Hamlin, 25, since he received lifesaving care after undergoing cardiac arrest on the field during an N.F.L. game on Jan. 2. Three specialists unanimously cleared Hamlin to return to football in April and he participated with teammates in drills last week during the team’s first off-season workouts.
