CNN —Wearing a helmet and seemingly in good spirits, Damar Hamlin participated in full practice with the Buffalo Bills for the first time since his cardiac arrest in January. Hamlin (left) participates in practice on June 6. On the sideline, Hamlin threw his helmet to the ground in frustration and trainers looked at his right shoulder/arm area. CPR was performed on Hamlin when he lost his pulse and needed to be revived through resuscitation and defibrillation. The 25-year-old was cleared to resume football activities last month and said he has been planning to make a comeback to the NFL.
