The Saints’ corresponding roster move is not yet known.
The Saints have now signed three veteran linebackers in the past three weeks while dealing with a series of injuries at the position. They signed Jo-Lonn Dunbar two weeks ago and Mike Mohamed last week.
New Orleans linebackers Hau'oli Kikaha (ankle), Dannell Ellerbe (hip) and Ramon Humber (hamstring) all missed Sunday’s game against the Tennessee Titans, though none are believed to be long-term issues.
Anderson, 32, was a starter for three-plus seasons in Carolina and for another season with the Chicago Bears in 2013. He has also spent time with the New England Patriots, Tennessee Titans and Atlanta Falcons. But he was not with a team this season.
The 6-foot-2, 235-pounder has 561 career tackles with five forced fumbles, three interceptions and 22 pass defenses.
