Saints signed DL Jimmy Wilkerson to a one-year contract. Wilkerson, 29, offers versatility as a swing-type tackle/end and is coming off a career year (6 sacks, 13 QB pressures), but tore his ACL in December and isn't sure to be ready by Week 1. Once healthy, he'll compete for snaps off the bench with LE Alex Brown and nickel pass rusher Bobby McCray.
