Defensive tackle Domata Peko (knee) and safety Chris Crocker (ankle) finished the week the way they started it and didn't practice Friday, usually an indication they won't play Sunday against the Chiefs. Both are listed as doubtful. Everybody else is probable. Defensive end Frostee Rucker missed his second straight practice with an illness. Defensive end Robert Geathers (knee) surfaced on the injury report Friday and didn't practice. Defensive tackle Tank Johnson (foot) went full go after being limited Thursday.
