Concerned that the videotape seized from the Patriots ended up in the hands of Fox Sports, the NFL is conducting an internal investigation as to how the tape was released. NFL spokesman Greg Aiello said the league is "very concerned; it should not have happened." Portions of the video, seized from Patriots video assistant Matt Estrella during the Sept. 9 season opener against the Jets, were aired on Fox's pregame show this past Sunday. The footage showed Jets assistant coaches signaling to players on the field, then panned to the scoreboard to indicate what down it was and what distance was needed to reach a first down.
