The game was originally scheduled to be played at 1:25 p.m. at CenturyLink Field and televised by FOX. That schedule has been changed, and the game will now start at 5:20 p.m. and be televised by NBC as its Sunday Night Football broadcast.

The game between the 49ers and Seahawks could be for the division lead. San Francisco is 9-3-1, currently a game and a half ahead of Seattle. The 49ers play at New England next week while the Seahawks face Buffalo.

San Francisco has won the last four games against Seattle, including three in a row since Jim Harbaugh became the 49ers' head coach.

It is the third prime-time game for the Seahawks this season after they hosted Green Bay on Monday night in Week 3 and played at San Francisco on Thursday night in Week 7.

Here's how the NFC West stacks up with three games remaining and a chance that three different teams could finish with a winning record this season:
