ORCHARD PARK, N.Y. -- Just over 3½ months after commotio cordis caused Damar Hamlin to collapse on a football field in Cincinnati, Hamlin sat in the Buffalo Bills' facility and officially announced his plans on making a comeback to the NFL after being fully cleared to return to playing football.
"This event was life changing, but it's not the end of my story," Hamlin said.
Hamlin shared Tuesday -- during his first news conference since the events on Jan. 2 during the first quarter of a regular-season "Monday Night Football" game against the Cincinnati Bengals -- that doctors concluded commotio cordis, "an extremely rare consequence of blunt force trauma to the heart that happens at exactly the wrong time in the heart rhythm, causing the heart to stop beating effective," per the American Heart Association, caused him to suffer cardiac arrest.
