IRVING, Texas -- Dallas Cowboys starting left tackle Tyron Smith left Sunday's 23-20 overtime win against the Cleveland Browns with a high ankle sprain that puts his availability for the team's Thanksgiving Day game against the Washington Redskins in question.
Jermey Parnell replaced Smith, who didn't play in the second half, at left tackle. The Cowboys were already minus center Ryan Cook (knee) and moved starting right guard Mackenzy Bernadeau to center. Derrick Dockery replaced Bernadeau at right guard in the starting lineup.
The Cowboys' offensive line had many issues Sunday, including a season-high seven sacks allowed and 10 hits on quarterback Tony Romo.
"It's high ankle, which just bothers the daylights out of ya," Cowboys owner Jerry Jones said of Smith's injury.
Jones later added: "The trainers were a little more than usual optimistic that it won't be as bad as it can be on high ankle."
Running back Felix Jones finished with 43 yards on 14 carries and one touchdown Sunday despite tweaking his left knee in the first half.
"Saw a lot of heart and saw him running hard," Jerry Jones said. "He actually had a little compromising situation with his left knee. But came back out there, this is a good sign, and he played on that."
Wide receivers Kevin Ogletree (concussion) and Dwayne Harris were hurt late in the fourth quarter. Ogletree said he passed a concussion test, but he didn't return after taking a hard hit under the chin on an incompleted pass. Harris was shaken up for an undetermined injury but later returned.
Also for the Cowboys, defensive lineman Josh Brent (pinkie) left the locker room with a splint on his finger, running back Lance Dunbar had a minor procedure done on his knee, and safety Danny McCray (hip) left the game briefly to get a pain medication shot.
