No practice for Kyle Kosier, Marc Colombo

IRVING -- The first regular-season practice is under way, and two offensive line starters, Kyle Kosier and Marc Colombo, missed things as they still recover from knee injuries.

Both players, with their right knees wrapped, did rehab work while Montrae Holland (guard) and Alex Barron (tackle) got reps with the first team.

The status of Kosier and Colombo for the season opener won't be known until later in the week.

Roy Williams, who missed last Tuesday's full practice with a lower back strain and a hip flexor, returned to practice.

Keith Brooking (shoulder), Marcus Spears (knee) and Gerald Sensabaugh (shoulder) also practiced.
