Baltimore Ravens vs Pittsburgh Steelers is the Sunday Night Football game this week with a fiercely intense rivalry set to resume between the top two placed teams in the AFC North.

The game is scheduled to start at 8.20 p.m. ET and can be watched online through free live stream (details below).

The Baltimore Ravens are currently top of the AFC North with a record of 7-2. However, they are closely following by the Pittsburgh Steelers in second who are just a game behind them on 6-3 and who could catch them with a win today.

This is a huge game in determining who will clinch the AFC North divisional title. This is in fact the first of a double-header between these two teams over the coming weeks, and the Ravens will again meet the Steelers in two weeks time.

Ravens coach John Harbaugh has said coming into this game: "This is a defining type of rivalry. It means so much to both teams."

Steelers coach Mike Tomlin has also said: "It's about physicality. It's about playing good hard-nosed football."

Steelers safety Ryan Clark has also added his take, saying: "These are the games that are the most competitive."

Both sides have suffered through key injuries this season, with the Ravens losing linebacker Ray Lewis and cornerback Lardarius Webb, which led to them allowing through a lot more rushing yards as a result.

The Steelers have also had their problems with their offensive line when their running backs were injured, and they have a big problem now that quarterback Ben Roethlisberger has been injured.

According to ESPN on Nov. 18 the Steelers' quarterback could miss as many as three weeks with his new shoulder injury, and his return date could be as late as Dec. 2 against the Baltimore Ravens. He will be sorely missed but the Steelers will have to find a way to operate without him today in this fierce encounter.

These two teams are evenly matched and it should be a great game.
