Updating a previous report, Koppen is confirmed to have sustained a torn ACL on Sunday, the
Denver Post reports.
ANALYSIS
The results of his exam reportedly confirmed that Koppen did sustain a torn left ACL in practice Sunday. With J.D. Walton likely out for the season following ankle surgery, the Broncos may have to turn to free agency to fill the void left at center. Manny Ramirez, Philip Blake, and Quentin Saulsberry all have some experience at the center position as well for the Broncos.
