Lattimore (abdomen) participated in the Saints' practice Wednesday in a limited capacity.
Lattimore hasn't played since Week 5, so his ability to practice Wednesday -- albeit in limited fashion -- suggests that he is at least improving. Per Ian Rapoport of NFL Network, the veteran cornerback has been dealing with a lacerated kidney, among other issues. If Davenport can return Sunday, it would be a boost to New Orleans secondary' against a 49ers passing attack that posted four touchdowns Monday against Arizona.
