Pittsburgh Steelers running back James Conner left Sunday's loss to the Seattle Seahawks in the fourth quarter with a knee injury.
It's unclear when Conner suffered the injury, but head coach Mike Tomlin told reporters after the game his running back was being evaluated by the medical staff.
The 24-year-old had 33 yards and one touchdown on 11 carries in Pittsburgh's 28-26 loss.
Pittsburgh's offense was beat up by the Seahawks. In addition to Conner's injury, The Athletic's Gerry Dulac reported Ben Roethlisberger will have an MRI on the elbow injury that caused him to sit out the second half.
