The Carolina Panthers continue to run short at running back as Chris Ogbonnaya suffered a groin injury at practice Friday.

If Ogbonnaya cannot play Sunday, Jonathan Stewart and Darrin Reaves would be the only healthy running backs against the Seattle Seahawks. DeAngelo Williams will miss a fourth straight game with an ankle injury, and Fozzy Whittaker is out with a quadriceps issue.

Coach Ron Rivera said Tauren Poole could be signed off the practice squad if necessary.

The Panthers also will be without both starting guards as left guard Amini Silatolu (calf) and right guard Trai Turner (knee/ankle) will be replaced by undrafted rookie Andrew Norwell and journeyman Fernando Velasco.

Also out are nickel corner Bene’ Benwikere (ankle), linebacker Chase Blackburn (knee) and kick returner Philly Brown (concussion).

Rivera said return duties will be handled by Brenton Bersin, Reaves and/or Jerricho Cotchery.
