Gibson (shin) doesn't have an injury designation for Sunday's game in Las Vegas, Nicki Jhabvala of The Washington Post reports.
Gibson's practice reps remain limited due to a stress fracture, but he hasn't missed a game all year and has three in a row with 19-plus carries since a Week 9 bye. He now has a chance to add some extra snaps (and targets), with J.D. McKissic (concussion) out for at least one game and possibly more. The other options to fill McKissic's snaps are rookie Jaret Patterson and practice-squad player Wendell Smallwood.
