Cowboys LT Tyron Smith sustained a high-ankle sprain in Sunday's win over the Browns.
Owner/GM Jerry Jones said it's not as bad as a high-ankle sprain can be, but we'd still consider Smith very unlikely to play on Thanksgiving. It's a major concern for the Cowboys, who were already playing without C Ryan Cook (knee). They gave up seven sacks and allowed 10 hits on Tony Romo Sunday. Journeyman Jeremy Parnell is Smith's backup.
