Conner was inactive for the Steelers' 24-21 defeat against the Oakland Raiders on Sunday. Rookie Jaylen Samuels led the team's rushing attack on the day with 11 carries for 28 yards, though he added a more impressive 64 receiving yards on seven catches. Veteran Stevan Ridley scored the team's lone touchdown on the ground.
The 23-year-old Conner, a third-round pick in the 2017 NFL Draft, has 1,376 yards from scrimmage and 13 total touchdowns on the season.
The Week 14 loss to the Raiders dropped the Steelers to 7-5-1 on the season. Pittsburgh remains just a half-game ahead of the Baltimore Ravens (7-6) for the top seed in the AFC North.
