Morris Claiborne is a full participant in practice

IRVING, Texas -- The first injury report of the week had some good news involving the secondary.

Cornerback Morris Claiborne was a full participant in practice on Wednesday. Claiborne missed his first NFL game with a concussion, suffered in the victory over Cincinnati on Dec. 9.

Claiborne also suffered a cut lower lip that required several stitches to close the wound. He now has a scar on his lip and he joked coca butter will get rid of it.

Claiborne said he expects to play in Sunday's game against New Orleans.

"I don't have no doubt in my mind," he said. "I expect to be on the field. I believe (the headaches) it's past me. I'm just going out there practicing and don't hold nothing back and whatever happens, happens."

Safety Charlie Peprah (foot) was also a full participant in practice on Wednesday and got work with the first-team defense.

Linebacker Ernie Sims (concussion) didn't practice but passed a concussion test. He has to undergo another one on Thursday.

Wide receiver Dez Bryant (finger) and outside linebacker DeMarcus Ware (elbow) were limited in practice. Bryant wore a splint and Ware a brace as they practiced.

Running back DeMarco Murray (foot) didn't practice, but that was expected because he normally doesn't participate early in the week.
