Broncos center Dan Koppen may have suffered a torn ACL during Sunday morning's practice, according to Jay Glazer of Fox Sports. He says the team officials "fear" it's a major knee injury, while Jason LaCanfora of CBS is hearing that Koppen's MRI results are not good.
Considered a possible departure this offseason, Koppen re-signed with the team after J.D. Walton suffered a setback to the dislocated ankle that ended his 2012 season. Koppen's backup, C.J. Davis, is also injured.
Peyton Manning got used to stability at the center position in Indianapolis thanks to Jeff Saturday's consistent Pro Bowl play. In Denver, he has been dealing with a laundry list of players snapping him the football.
We can add guard Manny Ramirez to the list of Broncos who have snapped the ball to Manning. With the center depth chart in shambles, Ramirez is tasked with making the position change, according to the Denver Post. It's still early in camp, so Denver could find a replacement center once more is known about Koppen's injury.
