Grady Jackson, who led the Oakland Raiders in sacks two years ago, signed a two-year contract with the New Orleans Saints on Thursday. Jackson, who will be entering his sixth season, played for the Raiders since he was selected in the sixth round in 1997. He started 32 of 67 games, posting 216 tackles, 19 sacks and four forced fumbles. He will take the place of La'Roi Glover, who signed with Dallas. Jackson, 6-foot-2, 330 pounds, emerged as a starter for the Raiders over the last two years. In 2000, he led Oakland with eight sacks and had 68 tackles and started 15 games. He started all 16 games last season, finishing with a career-best 69 tackles and four sacks.
