I'm not saying I believe the report. Time will tell though.
If it is a broken neck, then yes this could affect breathing and the heart. Maybe some of you remember the actor Christopher Reeves? Here's the video with the angle of the hit I saw and ran with. From this video, IMHO it sure looked like a head to head collision to me. Later, I saw another video with a different angle. It appeared from that video that there was no head to head contact, but a more normal chest and shoulder contact and tackle.
