Cam Newton took several helmet to helmet hits in the Carolina Panthers' 21-20 loss to the Denver Broncos.
Referees only penalized the Broncos on one of the hits, which was actually offset by Newton being called for intentional grounding.
"It starts with the guys who control the behavior on the field," Cecil Newton told ESPN on Friday. "I think the culprit is the mere fact that they allowed the game to get out of control. They allowed players to push the envelope to the very edge. That's my ultimate concern. Whether [league officials] want to go after them or not, fine. But I'm thinking about Cam Newton being healthy today, tomorrow and 25 or 35 years from now."
Newton was not given a sideline test at any point during the game despite their concussion protocol.
"If the league is going to be married to concussion protocol, first of all, start it with the officials because they mandate behavior on the field," Cecil Newton said. "If you're going to be married to the concussion protocol, be consistent with the calls that you're going to get, whether it's Cam vs. Aaron Rodgers or it's Aaron Rodgers vs. Ben Roethlisberger. I didn't see that at all last night. I didn't see any of that at all. And I am grossly disturbed about what I saw."
"It's not my place to question the officials," Newton said after the game. "I really like the officiating crew. It wasn't something I know they did intentionally, but it's not fun getting hit in the head.
"We didn't lose the game off that. I know that for a fact."
