The New England Patriots have acknowledged that their production crew inappropriately filmed the field and sideline during Sunday's game between the Cincinnati Bengals and Cleveland Browns.

The crew was credentialed by the Browns to shoot video for a web series entitled "Do Your Job," but the Patriots did not inform the Bengals or the NFL, which they called "an unintended oversight."

"The sole purpose of the filming was to provide an illustration of an advance scout at work on the road," the Patriots statement read. "There was no intention of using footage for any other purpose."

The Patriots also said the production crew, which included independent contractors who shot the video, is not part of New England's football operation.
