OXNARD, Calif. -- The Cowboys offensive line suffered another injury setback Wednesday afternoon.
Guard Nate Livings hyperextended his knee during the second half of the afternoon practice. He didn't return, but team officials are not calling it serious. Livings joins Bill Nagy (ankle), Kevin Kowalski (ankle) and Mackenzy Bernadeau (hip and knee) as interior linemen dealing with injuries. Ronald Leary replaced Livings with the first team when he went out.
*Nose tackle Jay Ratliff (foot) and safety Gerald Sensabaugh (knee) missed the afternoon practice as a precaution. Ratliff gets a bulk of his work during the morning walkthroughs while Sensabaugh does his rehab work. Sensabaugh said he's not trying to rush back onto the practice field and is waiting to be cleared by trainers.
*Tight end John Nalbone missed practice for personal reasons.
