Pittsburgh Steelers running back James Conner has entered the concussion protocol after being taken to the locker room during Thursday night's 52-21 victory over the Carolina Panthers, according to NFL.com's Austin Knoblauch.
The 23-year-old had 65 yards and one touchdown on 13 carries before exiting the game. Veteran Stevan Ridley (eight carries for 26 yards) helped close out the game.
A backup behind Le'Veon Bell during his rookie season, Conner recorded 32 carries for 144 yards. He suffered an MCL injury in Week 15 that resulted in him being placed on injured reserve.
