Sunday Night Football this week will be contested by the San Francisco 49ers and the Denver Broncos in a massive clash between two of the best teams in the league.

The game takes place from Sports Authority Field in Denver, Colorado and will start at 8.30 p.m. EST. The big Sunday Night Football game will be broadcast on the NBC network, but can also be watched online through live stream - free for subscribers - via the link provided below.

Coming into this game the 49ers are 4-2 and face a formidable test to try and go on the road to take down Peyton Manning and his high flying Denver Broncos, who are 4-1.

Peyton Manning is just two touchdown passes away from matching Brett Favre for the NFL record, and many believe that he will be able to equal or even pass that record tonight. However, even if he does that will be no guarantee the Broncos will be able to win today against a strong albeit slightly inconsistent 49ers team.

Although much of the media circus tonight will be about records, Manning no doubt will be more focused on keeping pace in the AFC West.

"Two big games coming up," Manning has said ahead of the game, referring to the Broncos' game against the AFC West-leading Chargers next week. "That's plenty to think about."

49ers coach Jim Harbaugh has been full of praise for Manning ahead of the game: "Whenever he takes the field, he's just great all the time and that speaks volumes for the player that he is and continues to be. Just keeps doing it and doing it and doing it. Great. Great with a capital 'G' at the highest level."
