Ausberry has not practiced this week and did not attend Tuesday's workout as a spectator, like the rest of Oakland's injured players. Coach Dennis Allen was tightlipped when discussing the issue and didn't disclose the exact nature of the injury or what knee Ausberry hurt.
A seventh-round draft pick, Ausberry missed all of 2013 after suffering a serious shoulder injury during the Raiders second preseason game in New Orleans. He later underwent surgery and was placed on season-ending injured reserve.
Despite that, Ausberry was listed as Oakland's starter when the team released the first depth chart of camp.
