Practice report: No DeMarco Murray, Ryan Cook

IRVING, Texas -- Running back DeMarco Murray missed his second day of practice on Thursday with a sprained foot, leaving little doubt now that Felix Jones will start at Carolina on Sunday.

It's no surprise given how Cowboys owner/general manager Jerry Jones said Tuesday that he regrets not having Murray for the upcoming Carolina game.

Also missing practice was punter Chris Jones (knee), center/guard Ryan Cook (hamstring) and defensive end Sean Lissemore (ankle).

Outside linebacker Anthony Spencer (pectoral muscle) and center Phil Costa (knee) were at practice, though it's uncertain how much they'll do after both were limited Wednesday.
