The Colts could be without No. 2 receiver Anthony Gonzalez for as many as six weeks. Gonzalez left the team's win over the Jaguars on Sunday with a knee injury. The team hasn't elaborated on the it, but a source close to the wide out said he sprained a knee ligament and could miss two to six weeks. "I sure hope it's not a season-ending injury," Peyton Manning told the Indianapolis Star. "I hope he's back soon. He's a huge part of our offense."
