Sunday Night Football takes place tonight with a huge match up between the Seattle Seahawks and the Arizona Cardinals in a game that could decide who takes the number 1 seed spot in the NFC.

Today's big game will start at 8.30 p.m. EDT and will be broadcast on the NBC network. The game will also be available to watch online through live stream - free for subscribers - via the link provided below.

Coming into this weekend the Arizona Cardinals are just about holding on to the number 1 seed placement for the NFC. However, a win for the Seahawks today could send the Cardinals flying.

In the NFC West division the Cardinals are still to secure the title, and a couple of slip ups for them coupled with a surge by the Seattle Seahawks has seen then Seahawks pull up right behind the Cardinals with just two weeks of the season to go.

The 11-3 Cardinals could lose the top spot to the Seattle Seahawks who are on 10-4.

These two teams met in Week 12 and at that time the Seattle Seahawks won 19-3, completely locking down the Cardinals' offense, while wearing down the Arizona defense with ther rush game.

They will no doubt look to do the same in today's game, and whether the Cardinals have an answer to that today remains to be seen.

After today's game, the Cardinals will finish their regular season by going on the road to the San Francisco 49ers, where as the Seattle Seahawks will play the St Louis Rams at home.
