Bills' Damar Hamlin returns to full practice after cardiac arrest.

Buffalo Bills safety Damar Hamlin fully participated in team drills during an offseason training activity (OTA) practice, wearing his helmet for the first time since suffering cardiac arrest during a game in January. General manager Brandon Beane praised Hamlin's progress and said the next step will be for him to put on pads and tackle during training camp. Hamlin announced in April that he was physically cleared to resume playing and has been at every session open to the media since. He recently launched a CPR tour to support youth sports and community groups.
