Claiborne suffered a torn patellar tendon in last week’s win against the New Orleans Saints and is out for the season. The Cowboys, however, have yet to officially place him on injured reserve.
The Cowboys could look call up linebacker Keith Smith from the practice squad for the second time in three weeks with Bruce Carter out of Sunday’s game against the Houston Texans with a quadriceps injury. Smith played against the St. Louis Rams on Sept. 21 when Rolando McClain was unable to play because of a groin injury.
The Cowboys could look to activate safety Jakar Hamilton. They have a one-week roster exemption for him to practice after his four-game suspension ended. In order to play Sunday, he would have to be added to the active roster.
