Backup quarterback Jon Kitna was not dressed out for practice Tuesday. It likely is a precaution. He missed several practices in training camp with a sore back.
Punter Mat McBriar (abdomen), receiver Miles Austin (hamstring), cornerback Josh Thomas (hamstring), cornerback Terence Newman (groin), linebacker Bradie James (ankle), linebacker Orie Lemon (hamstring), offensive guard Kyle Kosier (back), center Phil Costa (knee), tight end Martellus Bennett (ankle), defensive end Marcus Spears (groin) and linebacker Bruce Carter (knee) also did not practice.
The Cowboys will not play their starters on Thursday night against the Dolphins.
