Injury Update: Could Smith and Martin miss Sunday's game for Dallas?

The second injury report of Dallas week is out:

There's no change for the Jets but Dallas had one starting offensive lineman miss practice and another apparently picked up a new injury today.

Smith missed the Cowboys' season opener with ex-Jet Chuma Edoga starting in his place, but the Cowboys still rushed for 122 yards and didn't surrender a sack all day. Losing Martin as well would be a major blow though.
