Stafford turned, appearing to attempt a hand-off to Logan, but Logan started to collapse before Stafford reached him, holding his leg. He and Stafford collided before the Ravens piled on both players. Logan stayed down, but eventually limped off the field under his own power.
Lions staff looked at him on the sideline, then got the cart and drove Logan back to the locker room. The team's official Twitter feed said it is an ankle injury.
Logan had one carry for two yards at the time of his injury. He'd returned one kick for 18 yards and one punt for seven yards. The Lions lead Baltimore 14-9 in the second quarter.
