Las Vegas Raiders DT Andrew Billings (leg), LB Jayon Brown (hand), TE Jesper Horsted (concussion) and CB Rock Ya-Sin (knee) did not participate in practice Wednesday, Dec. 7, and have been ruled out for Week 14. CB Tyler Hall (back) was limited during practice and is listed as questionable. RB Ameer Abdullah (hamstring), RB Brandon Bolden (calf), LB Curtis Bolton (ankle), S Duron Harmon (quadriceps), C Andre James (quadriceps), LB Denzel Perryman (wrist), S Isaiah Pola-Mao (ankle) and LS Trent Sieg (ankle) fully participated in practice and are not on the injury report. The Raiders did not hold a practice Wednesday, so the practice participation is an estimation.
