Amazing how we had the diagnosis within 5 mins of his collapsing. We sure it wasn’t from exerting himself before the hit?

Or a history of cocaine use?

I have been watching NFL since I was a child. Only one time have I seen a remotely similar incident: when Reggie Brown’s neck was broken and he stopped breathing on the field. They had to remove his face mask to do CPR before getting him onto a backboard and into an ambulance. Then they continued the game.

Dropping from a heart attack after a standard, nothing-out-of-the-ordinary tackle has never happened before.

“We sure it wasn’t from exerting himself before the hit?”

No, we aren’t. But that would be incredibly unusual as it has never happened after millions of hits in pro football, many of them visibly more violent than the hit in question. When a person is hit hard enough to cause severe injury they don’t jump up and then collapse. They stay down because they are hurt or unconscious.
