The Denver Broncos continued revamping their roster Thursday by releasing veteran defensive linemen Justin Bannan and Jamal Williams.
Williams, who turns 35 this year, was due $1 million next week and $4.2 million next season. Bannan was due $500,000 next week and $3.5 million next season.
The moves came one day after the Broncos cut nine-year veteran tight end Daniel Graham, who was due a $1 million roster bonus Thursday. Graham and Bannan both starred at the nearby University of Colorado.
The specifics of the deal were not revealed.
Vickerson had his best season in 2010, playing in 15 games and finishing with 42 tackles, two sacks, one interception and one forced fumble.
