Big day for football fans tomorrow. The NFL Network will reveal the 2013 schedule at 8 p.m. ET.

Let the countdown to the opener begin. And that game will be…

The obvious match-up seems to be Baltimore at Denver.

The Super Bowl champion always gets the primetime treatment with the first game on NBC. Usually, it’s a home game, but that won’t be the case this year. The Ravens will open on the road because of a scheduling conflict with the Baltimore Orioles, who are scheduled to play the Chicago White Sox at 7:05 p.m. ET on that date. The NFL, Major League Baseball and the two teams were unable to reach a compromise to allow the Ravens to open at home.

The Ravens’ road opponents include Denver, Pittsburgh and Chicago. Pittsburgh could be a possibility because of the rivalry factor, and the networks always like primetime games in Chicago.

However, Ravens-Broncos has the most juice for a season opener. It would be a rematch of last year’s playoff game and yet another chance to showcase Peyton Manning.

Speaking of Manning, he makes his first trip back to Indianapolis this year. You know CBS, NBC, and ESPN would love to have that game.
