The Broncos have fallen under the microscope of the NFL for possible impermissible videotaping of an opponent, The Denver Post has reported. Broncos chief operating officer Joe Ellis confirmed to the newspaper Friday that the league was reviewing the team's possible filming of the 49ers from before their London game of Week 8. The team's video operations director, Steve Scarnecchia, is on a "personal leave of absence" while the NFL's investigation takes place.
