The Dallas Cowboys will be without one of their best players tonight.
Left tackle Tyron Smith is out with a back injury that surfaced during Friday's practice.
The Cowboys will also be without cornerback Orlando Scandrick, who has been battling hamstring issues.
With Smith out, the Cowboys will go with swing tackle Chaz Green on the left side. Green filled in for five plays for Smith during the season opener against the Giants.
Never miss a local story.
Smith went to the sidelines that game with a stinger issue, and it's unknown whether the back issue is related.
Smith had started 55 straight games at left tackle for the Cowboys going into tonight. The last game he didn't start happened to be Week 11 in 2012. He missed the game in 2012 with an ankle injury.
He started every game for the Cowboys as a rookie in 2011, and also the past three seasons from 2013-15.
Scandrick, meanwhile, has been questionable all week and complained about his struggles in trying to play through the injury. Anthony Brown will start at nickel cornerback for the Cowboys.
Tony Romo, Darius Jackson, Kavon Frazier, Mark Nzeocha and Charles Tapper are also inactive for the Cowboys tonight.
On the Bears side, quarterback Jay Cutler is inactive as expected. That means Brian Hoyer will start for Chicago.
