The Titans announced the deal Thursday.
The 10-year veteran ranks ninth with 79 1/2 sacks over the past decade in the NFL. He also has forced 22 forced fumbles in 152 career games with his first nine seasons in San Diego. The 6-foot-3, 255-pound linebacker played all 16 games for Denver last season with 10 sacks, 36 tackles, an interception and two forced fumbles.
General manager Ruston Webster says Phillips is a flexible linebacker who adds to the Titans' pass rush with his play and experience.
Phillips has missed only eight games in his career. He becomes the second linebacker Tennessee has signed this month who played for Denver last season, joining Wesley Woodyard.
