Straight from the Nicktator's mouth on the weekly SEC conference call, Mark Ingram will play this weekend: "He’s practiced all week, running fast and cutting good. He’s ready to go."
This being Nick Saban, of course, we didn't get any more details than that. No word on if he's starting, if there's a limit to the number of carries he'll get, or anything else along those lines. Not that it really matters against Duke.
