Colts nation was rocked late last night when news broke that Peyton Manning was undergoing knee surgery to remove an infected bursa sac from his knee.

The notoriously resilient quarterback, who is roundly considered one of the best, if not the best, active quarterback in the entire NFL (and who is loved much more than that by locals), will miss the entire Indianapolis Colts training camp and most of their preseason games.

While Manning rarely plays more than a series or two in each of the four preseason games, his ability to start the first game of the season is also uncertain. That is a huge deal for Manning, who leads currently playing quarterbacks for the most consecutive games played, and trails only Brett Favre, who is currently in retirement limbo, for the all-time record.

The Indianapolis Star will have updates throughout the day on this late breaking news.
