So, I haven't seen anyone mention it and it appeared to be a very blatant and obvious penalty. I'm talking about the stuffed QB sneak where there was a no call for helping the runner.
NFL Rule 12, Section 1, Article 5
Article 5 No offensive player may:
(d) push or throw his body against a teammate to aid him in an attempt to obstruct an opponent
or to recover a loose ball.
This is a 10 yard penalty which would have resulted in a 4th down and 10, maybe 11.
