NEW YORK - The Lions and Saints are moving to prime time. And the NFL is switching networks that televise a different game the same day.

The Dec. 4 game between Detroit and New Orleans will be played on “Sunday Night Football” on NBC. Kickoff is set for 7:20 p.m. at the Mercedes-Benz Superdome.

The Colts-Patriots matchup was originally in that slot, but the NFL previously announced it was shifting that matchup to earlier in the day under the league’s flexible scheduling policy.

Indianapolis is 0-10 without injured quarterback Peyton Manning, robbing the matchup with Tom Brady and the Patriots of its luster.

On Monday, the NFL said the meeting between the two NFC playoff contenders would take its place.

Detroit is 7-3 heading into its Thanksgiving meeting with Green Bay. New Orleans also is 7-3 and coming off a bye.

Also in Week 13, Ravens-Browns moves to 3:05 p.m. CST on CBS, while Broncos-Vikings shifts to noon on Fox. CBS usually handles all away games for AFC teams, but the league has made an unprecedented move by switching that telecast to Fox.

The switch was done because Fox would have had only two early games that Sunday and CBS would have had seven. The breakdown now is three and six.

The NFL can use flex scheduling to ensure meaningful matchups Sunday night starting in Week 10.
