cornerbacks Josh Wilson (shoulder) and David Jones (Achilles’ tendon) practiced fully, Shanahan said.

Shanahan said the team hasn’t heard anything yet from the NFL on a penalty for  cornerback DeAngelo Hall for his outburst at an official in Sunday’s am the Pittsburgh Steelers.

Shanahan said of the upcoming game Sunday against the Carolina Panthers: “Our backs are against the wall.” He stressed the importance of playing well and winning going into the bye.
