Englewood, CO (World Wide Gamble) - The Denver Broncos added a pair of defensive linemen to their roster by signing Jarvis Green and Jamal Williams on Tuesday.

Green had spent each of his eight NFL seasons with the Patriots after New England made him a fourth-round pick in the 2002 draft out of LSU. In 2009, he totaled 36 tackles and one sack in 12 starts.

A two-time Super Bowl champion, the 31-year-old's best season came in 2006 when he posted career-highs of 7 1/2 sacks and three forced fumbles in 16 games. Over 121 career games, Green has amassed 232 tackles, 28 sacks and nine forced fumbles.

Williams had spent his previous 12 seasons with the San Diego Chargers, where he recorded 436 tackles, 13 sacks and one interception in 148 regular-season games.

"Jamal is a leader and a proven high-end player at his position," Broncos general manager Brian Xanders said. "He has anchored some of the NFL's best run defenses during his career, and we are fortunate to add him to our roster."
