Cowboys owner Jerry Jones said cornerback Mike Jenkins and an offensive lineman left practice early, and he ruled out cornerback Terence Newman for the season opener against the New York Jets.
Jones declined to identify the offensive lineman who left practice early, but Jason Garrett confirmed it was right tackle Tyron Smith. Both are undergoing MRIs today.
Jenkins has been trying to work back from a shoulder stinger suffered early in training camp.
Newman didn't practice on Wednesday, and Jones said the Cowboys are preparing to play without him.
