The Denver Broncos beefed up their defensive line Tuesday by signing end Jarvis Green and agreeing to terms with tackle Jamal Williams.
Terms of the deals with the unrestricted free agents weren't disclosed.
Last season, Green had 47 tackles in 13 games, including 12 starts. He has tallied 232 tackles and 28 sacks in 121 games since the Patriots drafted him in the fourth round out of LSU in 2002. He also has 36 tackles and five sacks in 15 playoff games.
"He has always been a very high-grade special guy," Patriots owner Bob Kraft said of Green on WEEI. "It's unfortunate in this business, you can't keep everyone you want to keep. You have to make decisions. There are a lot of things you have to balance."
"Jamal is a leader and a proven high-end player at his position," Broncos general manager Brian Xanders said in a statement released by the team. "He has anchored some of the NFL's best run defenses during his career, and we are fortunate to add him to our roster."
