Cornerback Morris Claiborne and guard Nate Livings missed practice Wednesday because of concussions. Claiborne went out of last week’s game at Cincinnati in the third quarter after a sideline collision with teammate Danny McCray. Livings missed some of the fourth quarter but was in the for the game-winning drive.
Linebacker DeMarcus Ware (elbow) also was among seven players not practicing Wednesday.
Running back DeMarco Murray (foot) sat out a second straight Wednesday practice. Safety Charlie Peprah (foot) and nose tackle Jay Ratliff (groin) also missed, along with receiver Dez Bryant (finger).
