The Fumble - NBC refused to show that fan running on the field during the 49ers-Giants game on Sunday Night Football, even though commentator Cris Collinsworth desperately wanted to talk about it. Well, be thankful for the Internet. According to NJ.com, 25-year-old David Atwood of Connecticut was responsible for running on the field and allegedly head-butting and spitting on members of MetLife Stadium security. And from these two fan videos, that's exactly what it looks like.
