This would not have been an expected move at the beginning of the season.
However, things change, and flexing gives the NFL the option to move a game out of the Sunday Night Football slot and that is what the league is doing for NBC on Dec. 5.
The league has shifted the Seattle Seahawks-San Francisco 49ers game to a 4:25 p.m. ET kickoff.
Moving into the evening will be the Kansas City Chiefs visiting the Denver Broncos.
The Chiefs have won four in a row entering Week 12, which will be after their bye week.
The Broncos are 5-5 and will play the Los Angeles Chargers this Sunday.
The NFL has flexed Chiefs-Broncos in Week 13 to Sunday Night Football.
Seahawks-49ers moves to 4:25 PM ET.
