The Facts: Apparently Manning had to go through another procedure on his knee to clean things out after having his bursa sac removed last month. What is the most concerning is not the second operation (which the Colts are denying), but that they cannot control the swelling in Manning's knee and any physical movement causes more swelling.

Diehards Line:In a blog entry published Thursday, SI.com's Mike Lombardi further noted that several people in the NFL assured him that Manning's knee is a huge concern for the Colts. Lomardi, fairly well-connected due to his past work as an NFL personnel man, went on to state: "There is MUCH more here than meets the eye." Again, this is just a rumor at this point but given the source and Manning's high profile, it's certainly worth noting. Stay tuned. We'll continue to follow along and watch for more.
