Even though 2013 NFL free agency does not open until 4PM this afternoon, Tuesday will undoubtedly be a busy day leading up to the event - particularly if a crazy Monday (with two high-profile wide receivers traded) was simply an appetizer.

The two big names for Buffalo Bills fans to monitor today are, of course, Ryan Fitzpatrick and Andy Levitre. The Bills have a major decision to make on Fitzpatrick's contract; there's a good chance that they'll release him today, unless a re-structured contract can be agreed to. Levitre, meanwhile, is one of the hottest names on the market, with at least six teams (including the Bills) already showing interest in the durable left guard. The other five teams, by the way, are the Chicago Bears, Denver Broncos, Indianapolis Colts, San Diego Chargers and Tennessee Titans.

Any Bills-related news that breaks throughout the day will be covered on the home page as soon as we can get to it. For every other rumor or breaking news story in the league today, this is your open thread. Enjoy the day, Bills fans!
