IRVING -- Cowboys rookie right tackle, Tyron Smith, did some mental reps with the first-team but didn't practice on Friday as he's still recovering from a hyperextended right knee. He is wearing a new knee brace and his status for Sunday's season opener at the New York Jets is uncertain.
Cornerback Mike Jenkins, with his right knee taped, will practice. He also has a hyperextended knee and it appears he will play on Sunday.
Center Phil Costa (knee) also practiced.
Cornerback Terence Newman (groin) did some ball drills before practice. Coach Jason Garrett said Newman will travel with the team but it's still not clear if he'll play. Team owner Jerry Jones ruled Newman out on Wednesday, but over the last two days, the veteran corner has been running at nearly full speed.
How much work the players will get was not known.
