The Broncos are apparently about to find out whether Manny Ramirez or Philip Blake can cut it as an NFL center.
Incumbent center J.D. Walton is out until at least late October following surgery in June to clean out an infection in his surgically repaired left ankle.
When that infection was discovered, Denver re-signed Dan Koppen, who had filled in for Walton quite admirably in 2012.
Now, it's feared that Koppen suffered a torn ACL during practice Sunday.
Backup guard/center C.J. Davis was carted off Saturday with a sprained ankle, although he was at Dove Valley Sunday with neither a boot nor crutches.
This potentially leaves Ramirez (a high school center who's played exclusively at guard in the NFL) and Blake (who took over at center after Walton graduated from Baylor) to handle a crucial line position.
Although he retired following one poor season in Green Bay, it wouldn't surprise us if Denver were to check in on Jeff Saturday, who was Peyton Manning's guy for twelve seasons in Indianapolis.
