The Denver Broncos released DLs Justin Bannan and Jamal Williams, the team announced Thursday.

Bannan signed a five-year, $22 million contract last March with $7 million guaranteed. A source confirmed Bannan had a $500,000 roster bonus due on the fifth day of the league year. Williams was scheduled to earn $3.5 million in base salary for 2011.

Williams signed a three-year, $16 million deal with the Broncos last March with $6 million guaranteed. A source confirmed Williams had a $1 million roster bonus due on the third day of the new league year. Williams was scheduled to earn $4 million in base salary for 2011.

The decision to jettison both players isn’t too surprising since the Broncos will be transitioning from a 3-4 to a 4-3 defense this coming season. The Broncos only have two defensive tackles now under contract--Louis Leonard and Ryan McBean.

The team released veteran TE Daniel Graham on Wednesday.

The Broncos saved $14.2 million in base salaries and bonuses for the 2011 after releasing the three players. Since they are vested veterans, they are not subject to the waiver process and are able to sign with another team immediately. However, they have until 12:00 a.m. ET to do so without a new CBA.
