The NFL has seen the preview for Esquire Network's new youth football reality show "Friday Night Tykes," and a spokesperson said it is "definitely troubling to watch."

The new TV show is about an elite, serious youth football league in Texas with players that are eight and nine years old. Coaches are portrayed as being very tough on the kids.

"Rip their freaking heads off and let them bleed," one coach is seen telling his players.

The preview also show multiple hard, helmet-to-helmet hits.

An Esquire Network representative said the show is supposed to be controversial.

"We believe it brings up important and serious questions about parenting and safety in youth sports, and we encourage Americans to watch, debate, and discuss these issues," she said.
