(AP) — The Denver Broncos and Buffalo Bills have filled their head coach vacancies, completing the task 10 days after the regular season ended.

The Broncos have selected Vance Joseph, who had served as one of the NFL's top secondary coaches before spending this season as the Dolphins' defensive coordinator. He replaces Gary Kubiak, who was hired over Joseph by Broncos vice president and general manager John Elway two years ago.

Joseph inherits a team that experienced a late-season swoon to finish 9-7, one season after winning the Super Bowl.

Sean McDermott has a much tougher task in Buffalo. He takes over a club that has hired eight other head coaches since 1999, the team's last playoff appearance. McDermott worked the last six years as the Panthers' defensive coordinator and helped Carolina reach the Super Bowl last season.

Meanwhile, Falcons offensive coordinator Kyle Shanahan says he doesn't know when he and the Rams will be able to reschedule an interview that was postponed last week due to weather. Shanahan has had interviews with officials from Denver, Jacksonville and San Francisco about their head coach openings and planned to discuss the same position with the Rams. He says his total focus has been on Saturday's NFC divisional playoff game against Seattle.
