NFL doubles down on conventional interference exacerbated by the weather as the culprit.

“Based on our review to date, we believe that the audio interference on Steelers’ headsets last night was entirely attributable to an electrical issue made worse by the inclement weather; that it involved no manipulation by any individual; and that the Patriots had nothing to do with it,” the league’s statement said. “The issue was promptly resolved and there were no further problems for the remainder of the game. We will continue to review the matter to determine if there are technical steps that can be taken to avoid similar problems from occurring in other games.”
