Tony Romo: (Undisclosed) No Practice Thursday

Romo (undisclosed) didn't take part in Thursday's practice, Todd Archer of ESPN Dallas reports.

Analysis:

Because the Cowboys take the field Monday against Washington, Romo is missing the first scheduled practice, which lands on Thursday this week. The precise cause of the absence is unknown, but his back or ankle could be ailing him again. Expect him to return to drills in some capacity before Saturday's injury report emerges.
