The Broncos are still scheduled to host 325-pound defensive tackle Terrance Knighton, but he won't be replacing Kevin Vickerson on the team.
According to Adam Schefter, Denver has agreed to terms on a new two-year deal with Vickerson, who had accepted a 46.7% pay cut (from $2.25M to $1.2M) to stay with the team in 2012.
In 17 games, Big Vick tallied a +3.6 grade on 537 snaps according to PFF, with two sacks, four QB hits, nine hurries, and a pass defensed. PFF credited him with 32 total tackles, 26 stops, and charged him with two missed tackles.
Justin Bannan, Denver's other starting defensive tackle, is also an unrestricted free agent.
