SANTA CLARA -- The 49ers traded outside linebacker Parys Haralson to the New Orleans Saints, a source told CSNBayArea.com.
It was not immediately known what the 49ers received as compensation for Haralson, 29, who is entering his eighth NFL season. Haralson, a fifth-round pick in 2006, started 68 games for the 49ers. He recorded 21.5 sacks. He missed all of last season with a torn triceps.
Saints veteran outside linebacker Will Smith is reportedly out for the season with an ACL injury.
Haralson walked through the 49ers locker room shortly before the start of the 49ers' 6 p.m. practice on Monday and said goodbye to many of the players in the 49ers' locker room. Running back Frank Gore told Haralson, "Go easy on me."
Haralson will get a chance to play against Gore and the 49ers on Nov. 17, when the 49ers travel to New Orleans.

The 49ers were looking to get younger and cheaper at backup outside linebacker behind starters Ahmad Brooks and Aldon Smith. Rookie Corey Lemonier, a third-round draft pick from Auburn, has played well during the exhibition season. And veteran pickup Dan Skuta, a key special-teams player, is also a backup. Also, second-year player Cam Johnson has also been much-improved from a year ago, but he left Sunday night's game against the Minnesota Vikings with a shoulder injury.
