The flamboyant Dallas receiver was not suspended.
NFL spokesman Greg Aiello announced the fine, which came after Hall knocked Owens out of bounds on a pass play during Dallas' 38-28 win.
"I got frustrated and I apologize for that," Owens told the NFL Network after the game. "It was a situation where he kept bugging me and getting in my face."
If the officials had seen Owens spitting, he would have been ejected from the game under NFL rules.
