FRISCO, Texas -- Tests confirmed that Tyron Smith suffered a high right ankle sprain in Sunday's loss to the New Orleans Saints, and the Dallas Cowboys Pro Bowl left tackle is week-to-week, according to coach Jason Garrett.
"It's hard to say anything definitively about him (Smith), but we did get some favorable results from the MRI," Garrett told reporters, according to the team's website. "So we're going to list him as week to week and just see how he responds over the next few days. We're still less than 24 hours out from the injury, so we'll just see how he responds coming in. But the initial results have been favorable."
Smith suffered the injury on the first play of the Cowboys' final, ill-fated drive when he was rolled into from behind as Dak Prescott was being sacked by David Onyemata. Smith was able to walk to the sideline before being taken to the locker room on a cart.
Cameron Fleming took over and will be called upon if Smith is unable to play Sunday against the Packers.
Smith has missed three games in each of the past three seasons due to injuries after missing just one game in his first five seasons. He has been dealing with a back issue at different times the past few years.
Pro Bowl defensive end DeMarcus Lawrence suffered a bruised right shoulder late in the New Orleans loss, but it is not expected to keep him out this week. He had offseason surgery on his left shoulder. Cowboys backup safety Kavon Frazier suffered a torn pectoral muscle and will go on injured reserve, Garrett said.
