Dan Koppen considered retirement before re-signing with the Denver Broncos this off season. Now the center has been lost for the season with ACL injury suffered in training camp.

The Broncos signed Koppen after J.D. Walton suffered an ankle injury. Now Denver will seek out another name for the position.
With camp beginning the market is thin with Jeff Faine, Eugene Amano, and Jason Brown the top available.
