A New Jersey judge dismissed an order of protection in favor of a woman who accused New York Giants player Kam Moore of cold-cocking her, then stomping on her neck — a sign that the case against the safety may be in trouble.

Superior Court Judge Frederic McDaniel on Wednesday dropped the protective order barring Moore from any contact with Hilda Polanco after determining that “the plaintiff’s allegation of domestic violence has not been substantiated,” court papers say.

His lawyer, Alex Spiro, called the ruling “vindication” for his client, who was suspended over the July 11 incident.

Polanco, who had been dating Moore since January, decided to drop by his house when he didn’t respond to her texts.

But another girlfriend was there, and the two women got into a brawl. After Polanco fell to the floor, Moore allegedly put his foot on her neck, then, when she got up, slugged her in the face.

Moore was charged with aggravated assault and aggravated assault as a domestic-violence incident.
