Panthers sign seven to practice squad

CHARLOTTE, N.C. -- Seven players released by the Carolina Panthers on Saturday were signed to the practice squad on Sunday after clearing waivers: WR Brenton Bersin, LB Ben Jacobs, S Robert Lester, RB Tauren Poole, DE Craig Roh, WR James Shaw and DT Casey Walker.

Don't be surprised if Carolina makes changes to the 53-player roster by Monday, with depth and experience still needed on the line and in the secondary.
