The 49ers-Seahawks game in Week 16 has been flexed to be on "Sunday Night Football" on NBC.
Seattle hosts the Niners in a game that could help decide the NFC West and will have seeding and playoff implications for both teams. At 9-3-1, the 49ers currently have a 1½ game lead over the Seahawks, who, at 8-5, hold one of the NFC's wild-card spots.
The originally scheduled Sunday night game between the Jets and Chargers at MetLife Stadium is moved to a 1 p.m. ET kickoff on CBS.
The league also flexed the Giants-Ravens game in Baltimore from a 1 p.m. ET kickoff to a 4:25 p.m. ET kickoff on Fox.
