Five starters not at full strength for practice

IRVING, Texas -- The Cowboys kicked off preparations for Sunday’s season opener at the New York Jets with three starters not practicing and two more working through rehab.

Cornerback Terence Newman (groin), defensive end Marcus Spears (groin) and center Phil Costa (knee) are sitting out, although Newman and Spears are doing on-field rehab work. Costa was riding the bike in the weight room.

Linebacker Bradie James (ankle) and wide receiver Miles Austin (hamstring) were in uniform but went through rehab in the portion of practice open to the media. Austin missed the last three preseason games and James missed the finale at Miami.

Tight end Martellus Bennett (ankle) was also sitting out of practice. He suffered a high ankle sprain on Aug. 27 at Minnesota and could be in doubt for the Jets game. Cornerback Mike Jenkins (stinger), right guard Kyle Kosier (back) and quarterback Jon Kitna (back) were practicing.
