NFL spokesman Michael Signora has issued the following statement regarding the Pittsburgh communications issue.
"In the first quarter of tonight's game, the Pittsburgh coaches experienced interference in their headsets caused by a stadium power infrastructure issue, which was exacerbated by the inclement weather. The coaches' communications equipment, including the headsets, is provided by the NFL for both clubs use on game day. Once the power issue was addressed, the equipment functioned properly with no additional issues."
