The 49ers-Seahawks game that could decide the NFC West is moving to prime time.

The NFL said Monday that San Francisco’s matchup with Seattle on Dec. 23 would be on NBC’s “Sunday Night
Football.”

Starting in Week 11, the league’s flexible scheduling policy allows it to move a more appealing game to Sunday night. This is the first time this season a switch has been made.

The 49ers are 9-3-1 heading into their trip to New England for the first of what will be two straight Sunday night appearances. The Seahawks are 8-5 and play Buffalo in Toronto this weekend.
