Cam Newton said he plans to talk to Roger Goodell about the no-calls he has been receiving on what appear to be hits to the head.

"It's really taking the fun out of the game for me -- honestly, it really is," Newton said. "At times, I don't even feel safe. Enough is enough. I plan on talking to commissioner Goodell about this. It's not fun, and I don't know what I have to do."

Newton said the breaking point came in the second half of the Panthers' 30-20 victory over Arizona on Sunday when he took a hard shot to the knees. 

"I could have torn an ACL. That was the breaking point for me," Newton said.

Newton used the words "bullcrap" and "horsecrap" in reference to his conviction that officials aren't making calls when he's hit in the pocket. Newton said other quarterbacks in the league get those calls more often.

"I showed a lot of frustration today, and I apologize to the referee I was talking to. But I don't think there's a person that can go through what I go through and keep their head, you know what I'm saying? Hits to the head, that's one thing, but when you're not protected in the pocket, that's another thing. It became the story of my life ever since I came in; it's always, 'Oh, we missed that, I'm sorry.' That's bullcrap -- that's bullcrap."
