DALLAS (105.3 The Fan) - Cowboys left tackle Tyron Smith is out for today's game against the Seahawks.

Sources informed 105.3 The Fan's Bryan Broaddus that Smith worked out pregame and "looked okay," but would "probably be down" for the game.

The Cowboys made it official when they announced the inactive list 90 minutes prior to kickoff.

Swing tackle Brandon Knight, who did a great job stepping in for Smith when he missed last week's win over Atlanta with the neck issue, will be called on once again to protect quarterback Dak Prescott.

The Cowboys did get some good news as both defensive end DeMarcus Lawrence (knee) and cornerback Trevon Diggs (shoulder) are active for the game.
