The Broncos suffered  a major setback Sunday as center Dan Koppen suffered a season ending injury.

Koppen tore his ACL during a training camp drill and will require surgery.

Denver will shift Manny Ramirez to center in training camp.  Ramirez is a fifth year veteran who started eleven games for the Broncos last year at right guard.

C.J. Davis is another center possibility for the team.  The lineman sat out of Sunday’s practice however with an ankle injury.
