IRVING, Texas -- Cowboys starting left tackle Tyron Smith left Sunday's game against the Cleveland Browns with a high ankle sprain that puts his availability for the Thanksgiving Day game with Washington 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 on 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. Later he 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 who finished with 43-yards and one touchdown on 14 carries, tweaked his left knee in the first half.

"Saw a lot of heart and saw him running hard," Jerry Jones said of Felix Jones. "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 of the overtime win. 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.

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 but returned after getting a pain medication shot.
