Welcome to prime time.

After an 8-1 start to the season, the 49ers have been flexed into two marquee games under the lights at Levi's Stadium: Week 12 against the Green Bay Packers and Week 16 against the Los Angeles Rams.

The 49ers-Packers game, originally scheduled for 1:25 p.m. on Nov. 24, has been moved to a 5:20 p.m. kickoff for "Sunday Night Football" on NBC. Iconic broadcasters Al Michaels and Cris Collinsworth will call the game from Santa Clara, as the NFC-leading 49ers take on Aaron Rodgers and the 8-2 Packers.

Meanwhile, the 49ers-Rams NFC West clash, originally scheduled as "TBD" for Saturday Dec. 21 or Sunday Dec. 22, officially will kick off at 5:20 p.m. on Saturday the 21st. The 49ers beat the Rams 20-7 in Los Angeles in Week 6, so Jared Goff and the underachieving Rams will try to get revenge under the lights at Levi's. The game will be broadcast on NFL Network.
